HOWTO: Fix: Error: Wordfence Update Error

If you see this error when updating Wordfence in the WordPress Dashboard...

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/*

Fix 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.
