SSL When Using A Reverse Proxy

If WordPress is hosted behind a reverse proxy that provides SSL, but is hosted itself without SSL, these options will initially send any requests into an infinite redirect loop. To avoid this, you may configure WordPress to recognize the HTTP_X_FORWARDED_PROTO header (assuming you have properly configured the reverse proxy to set that header).

define('FORCE_SSL_ADMIN', true);
// in some setups HTTP_X_FORWARDED_PROTO might contain
// a comma-separated list e.g. http,https
// so check for https existence
if (strpos($_SERVER['HTTP_X_FORWARDED_PROTO'], 'https') !== false)
$_SERVER['HTTPS']='on';

if (is_admin()) { 
    function jba_disable_editor_fullscreen_by_default() {
    $script = "jQuery( window ).load(function() { const isFullscreenMode = wp.data.select( 'core/edit-post' ).isFeatureActive( 'fullscreenMode' ); if ( isFullscreenMode ) { wp.data.dispatch( 'core/edit-post' ).toggleFeature( 'fullscreenMode' ); } });";

Performance Tweaks

Why Is WordPress Slow?

However, many factors can affect your WordPress site’s performance. Some of the most common ones include:

Your site’s web hosting provider
Server-side optimizations (PHP version, caching, compression, etc.)
Sluggish WordPress themes
Slow WordPress plugins
Unoptimized content (mainly images)
Too many external HTTP requests
Not using a dedicated resource to serve content (CDN, video hosting, etc.)

Caching

WordPress 6.1 and later now includes checks for Page Cache and Object Cache in the Site Health tool.

How do I disable the cache checks? Add these code snippets:-

function disable_full_page_cache_check( $tests ) {
    unset( $tests['async']['page_cache'] );
    return $tests;
}
add_filter( 'site_status_tests', 'disable_full_page_cache_check' );

function disable_object_cache_check( $tests ) {
    unset( $tests['direct']['persistent_object_cache'] );
    return $tests;
}
add_filter( 'site_status_tests', 'disable_object_cache_check' );

WordPress Caching

Caching strategy is a key decision for any WordPress site for speed and performance. There are typically 4 levels of caching recommended for WordPress. Here is a description of how we will set up caching for WordPress with Docker:

Browser Caching: This is what tells the visitors browser to cache the files locally to speed up future site/page visits. We will set this up using Nginx. On Apache, this is accomplished using .htaccess files.

Server Caching: This caches static versions of pages (Page cache). We are going to accomplish this using Nginx FastCGI cache.

Frontend Caching: This means caching WordPress PHP files so they don't have to be re-compiled for every visit. We are going to set this up using PHP OpCache.

Database Caching: This optimizes database queries by storing them in the RAM for faster delivery. We are going to use Redis for this.

As mentioned before, I have Cloudflare and Ezoic Site Speed+ that serve cached and optimized content to visitors. But even without those, the above caching strategy should deliver excellent speeds.

https://www.smarthomebeginner.com/wordpress-on-docker-traefik/

Here is a quick list of the different types of caching we can identify:

Page cache: it happens on the server and stores the entire HTML of a page (as WP Rocket does);
Browser cache: it keeps storing the HTML but occurs on the browser;
Object cache: it stores database queries;
Bytecode cache: it's a PHP extension and stores precompiled script bytecode in the memory;
CDN cache: it occurs on the CDN-side and stores the HTML and all other static files (images, CSS and JS);
Reverse proxy cache: it happens on the server's side and stores all its responses to the client's server.

Browser Caching

For Apache .htaccess ...

Accessibility Skip To Main Content

One of the earliest solutions in all of web accessibility was the "skip to main content" link, a same page link at the top of the page that enables users to skip past navigation links and go straight to the main content of the web page. Despite the fact that these links have been in use since the early 1990's, they actually aren't implemented well at all by browsers. They can be a huge benefit to sighted non-mousers (navigating by keyboard) but they don't work for these users in any browser other than Firefox and Internet Explorer, and they don't even work in IE unless link targets have tabindex="0".

<div id="skiplink-container">
   <div>
     <a href="#content" class="skiplink">Skip to main content</a>
   </div>
 </div>
 
 <div>
   <main role="main" id="content" tabindex="-1">
   ...

How to add more Columns

The default columns block uses two columns, but you can add up to six columns in one column block.

To increase the number of columns, click somewhere in the column block but outside of the blocks within it. You'll see the settings in the sidebar switch from the Document settings to the Block settings revealing extra options. You can use the slider or the number input to adjust the number of columns from 2-6.

Using Oxygen with Elementor

Yeah, I know, why the **** would you want to? But, it's possible ...

Oxygen > Templates > New Template > Add Sections for header + main + footer, then in the main section add a Code Block with the PHP ...

<?php the_content(); ?>

... and then you can install the Elementor plugin, edit the page and watch as 100's of lines are added to your code :)

But, it's easy to use, right?

CSS clamp()

CSS clamp is a function that sets responsive unit sizes without any media queries. The function takes 3 parameters in this order:

min - where to start scaling from.
viewport width - the range determines how fast the min scales to the max based on the screen getting larger.
max - when to stop scaling.

How To Clone A Template

Under "Edit with Oxygen" you can click on shortcode and copy the content, then create a new template, click on shortcode, paste it and save it. Done.

How To Copy An Entire Web Site

To copy an entire WordPress install with all of your content, plugins, settings, and everything else, you can use a plugin like All-in-One WP Migration.

Once you've created a .wpress package with All-in-One WP Migration, import the package on the target site and do the following:

Save your permalinks twice via Settings > Permalinks
Resign your shortcodes via Oxygen > Settings > Security
Regenerate your CSS cache via Oxygen > Settings > CSS Cache
Check to verify that everything looks and works as you expect

You may also need to open each template in the admin area and click the Update button on the right-hand side, but this is rare if you have followed the above steps.

Command Line Updating Database

This will update the WooCommerce database using wp-cli on a WordPress Multisite install...

export WP_CLI_CACHE_DIR=/var/www/domain.co.uk/.wp-cli/cache; sudo -u www-data -E wp --path='/var/www/domain.co.uk/html/' --url='https://sub.domain.co.uk/' wc update

Square Payment Plug-In

The Square Digital Wallet option for WooCommerce is lovely and all, but it means you can get around the Order Limit plug-in.

The fix?

Install the WPCode Lite plug-in then add a PHP Snippet called 'WooCommerce Square Hide Digital Wallet' with this code in it ...

add_filter( 'wc_square_display_digital_wallet_on_pages', function( $pages ) {
    return array(
        /* 'product', // Don't show Apple Pay and Google Pay on product pages */
        /* 'cart', */
        'checkout',
    );
}, 10, 1 );

Network Activate Plugins

On a WordPress multisite, only Super Admins can install plugins. After the installation, super admins have these options...

Network Activate – Using this option super admins can activate a plugin across the network.
Activate – They can also activate a plugin for the main/root site.
Individual Sites – Lastly they can allow individual site administrators to activate plugins themselves.

When you log in to your WordPress multisite's main site, you will be able to see two different plugins screen.

The first one is on the main admin sidebar. It is for plugins installed and available for activation on your main site.

The second plugins screen is located under My Sites » Network Admin » Plugins. This is where you will install new plugins and manage them for the entire network.

https://www.wpbeginner.com/beginners-guide/should-you-network-activate-all-plugins-on-wordpress-multisite/

Add Plugins Menu for Child Sites in WordPress Multisite

To enable plugin’s menu for individual sites, you need to switch to Network Admin dashboard.

Switching to network admin dashboard

On the network admin dashboard, visit Settings » Network Settings. Scroll down to the bottom of the page and you will see the checkbox to enable plugins menu.

DEBUGGING

The following code, inserted in your wp-config.php file, will log all errors, notices, and warnings to a file called debug.log in the wp-content directory.

It will also hide the errors so they do not interrupt page generation.

// Enable WP_DEBUG mode
define( 'WP_DEBUG', true );

// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );

// Disable display of errors and warnings
define( 'WP_DEBUG_DISPLAY', false );
@ini_set( 'display_errors', 0 );

// Use dev versions of core JS and CSS files (only needed if you are modifying these core files)
define( 'SCRIPT_DEBUG', true );

NOTE: You must insert this BEFORE /* That's all, stop editing! Happy blogging. */ in the wp-config.php file.

HOWTO: Disable wp-cron.php WP_CRON

WordPress uses a file called wp-cron.php as a virtual cron job, or scheduled task in order to automate things like publishing scheduled posts, checking for plugin or theme updates, sending email notifications and more.

By default WordPress is set up to call wp-cron.php every time someone visits your WordPress website when a scheduled task is present, to basically ask "is it time to do anything yet?".

On low traffic sites this is perfectly fine, but when visitors roll in, checking multiple times for scheduled tasks can be very inefficient and lead to resource usage problems for your server, plus make your website load slower.

To fix this, change the following setting in your wp-config.php file...

define('DISABLE_WP_CRON', true);

Then, create a cron job to call the script...

crontab -e
@hourly cd /var/www/website.co.uk/html/ && sudo -u www-data php wp-cron.php

or

@hourly curl --silent https://www.website.co.uk/wp-cron.php?doing_wp_cron

IONOS Tweaks

Out of the box, the IONOS Linux hosting seems to use PHP 7.3 for wp-cli ...

wp cli info

To fix this, select your PHP version in the admin panel - e.g. 7.4

Log in to your hosting server using SSH, then check to make sure this test works ...

/usr/bin/php7.4-cli /usr/share/php/wp-cli/wp-cli-2.6.0.phar cli info

Then, assign a terminal shall alias to 'wp' for the second test and run 'wp' ...

alias wp='/usr/bin/php7.4-cli /usr/share/php/wp-cli/wp-cli-2.6.0.phar'
wp cli info

Then, create a few files to automatically load the alias and fix it ...

nano ~/.bash_profile
alias ll='ls -lah'
alias wp='/usr/bin/php7.4-cli /usr/share/php/wp-cli/wp-cli-2.6.0.phar'

nano ~/.bashrc
source ~/.bash_profile

Log out, then back in and type ...

wp cli info

... and it should now show the later version of PHP being used.

sudo -u www-data wp user create joe.bloggs joe@bloggs.com --role=editor --display_name=Joe Bloggs --first_name=Joe --last_name=Bloggs

User Reset Password

1. Move into the /wordpress directory and type

sudo -u www-data wp user list

to see all users. Find the ID of the user you'd like to update.

2. Then, update the user

sudo -u www-data wp user update 1 --user_pass=changeme --skip-email

replacing "1" with the id of the user you want to update.

Check A Post For Type

sudo -u www-data wp post get 230

Show WordPress URL

wp option get home
wp option get siteurl

Change WordPress URL

wp option update home 'http://example.com'
wp option update siteurl 'http://example.com'

Search and Replace and View Changes

sudo -u www-data wp search-replace 'Lorem ' 'Lorum ' --dry-run --report-changed-only --log

Search and Replace WordPress Database Change URL

sudo -u wpusername wp search-replace 'http://test.domain.co.uk' 'http://www.domain.co.uk' --dry-run
sudo -u wpusername wp search-replace 'http://test.domain.co.uk' 'http://www.domain.co.uk'

or for auto SSL sites...

sudo -u wpusername wp search-replace 'http://test.domain.co.uk' 'https://www.domain.co.uk' --dry-run
sudo -u wpusername wp search-replace 'http://test.domain.co.uk' 'https://www.domain.co.uk'

Export All Users

This will export all users to a CSV...

sudo -u daemon -E wp --path=/opt/bitnami/apps/wordpress/htdocs/2 user list --format=csv >user_list.csv

Block A User

change their password
change their role
change their email address

export WP_CLI_CACHE_DIR=/var/www/www.domain.co.uk/.wp-cli/cache/
sudo -u www-data wp --path=/var/www/www.domain.co.uk/html/ user list
sudo -u www-data wp --path=/var/www/www.domain.co.uk/html/ user update 2 --user_pass=iphoh3Qu --skip-email
sudo -u www-data wp --path=/var/www/www.domain.co.uk/html/ user update 2 --role= --skip-email
sudo -u www-data wp --path=/var/www/www.domain.co.uk/html/ user update 2 --user_email=different.email@domain.co.uk --skip-email
sudo -u www-data wp --path=/var/www/www.domain.co.uk/html/ user list

Delete All Subscribers

For this trick, you have to combine 2 commands in to 1... generate the list of users + feed that result to the delete command...

$ wp user delete $(wp user list --role=subscriber --field=ID) --reassign=2

Do the Export All Users first!

This is an example from a Bitnami WordPress install, using the user 'daemon' and the full path for completeness...

sudo -u daemon -E wp --path=/opt/bitnami/apps/wordpress/htdocs/2 user delete $(sudo -u daemon -E wp --path=/opt/bitnami/apps/wordpress/htdocs/2 user list --role=subscriber --field=ID) --reassign=23

Delete Comments

wp comment delete $(wp comment list --status=spam --format=ids) --force

or

wp comment delete $(wp comment list --format=ids) --force

Perform Commands Remotely

WP-CLI accepts an --ssh=[<scheme>][<user>@]<host>[:<port>][<path>] global parameter for running a command against a remote WordPress install.

First, install wp-cli on your computer...

sudo add-apt-repository ppa:tiagohillebrandt/wp-cli
sudo apt-get -y install wp-cli
sudo -u www-data wp --info

Then, use a host entry in your ~/.ssh/config file for your server, then you can run this...

wp --ssh=host --user=jbloggs --path='/var/www/domain.com/html' core version

Error: changeset_post_save_failure

This is caused by a faulty PHP file in the WordPress installation and a possible MySQL database corruption.

Use wp command line to backup the database, then clear the database, then force upgrade the WP install.

sudo -i
sudo -u www-data -E wp db export wp_db_export_file.sql
chown www-data:www-data wp_db_export_file.sql
cp -av wp_db_export_file.sql ~/

Installing Plugin: Wordfence Security x.x.x
Downloading install package from https://downloads.wordpress.org/plugin/wordfence.x.x.x.zip…
Unpacking the package…
Could not copy file. wordfence/xxxxx/xxxxxx

You need to go to /wp-content/upgrade/ and delete all the wordfence folders/files in there. Chances are you won't be able to do that via FTP due to chown problems but will need shell access to your server to get rid of them. After that is done you will be able to upgrade without a problem.

cd /home/user/www/wp-content/
sudo rm -rfv upgrade/*

Updates On Hosting With 1&1

The problem I was having was the update would start, and then just stop after a few seconds.

Then in my wp-content folder I would see a bunch of failed downloads. They were the update zip files with a 0 byte size.

The Solution:

Add the following line to your .htaccess file in the root directory of your blog.

AddType x-mapp-php5 .php

This will enable PHP version 5 + on your blog and then your update should take off.
