Fix UNINSTALL_WPSUPERCACHE Must Be Set To A Non-blank Value

In my post about Techie Buzz’s Architecture, I had stated that I used a WordPress plugin for caching   called W3 Total Cache. I love that plugin and have been using it for over a year now. However, prior to that I used another popular caching plugin called WP Super Cache which did the job well too.

However, I removed the plugin for some reasons and started using W3 Total Cache instead. Today, while performing a regular maintenance, I decided to remove plugins that I am not using anymore. One of the plugins I was removing was WP Super Cache. However, while uninstalling the plugin I was getting an error:

UNINSTALL_WPSUPERCACHE must be set to a non-blank value in uninstall.php

The problem was that it was looking for a non-empty value for a field. Now, I could have simply deleted the plugin folder using FTP, however, it would mean that there would be unwanted settings and files lying around on the server. However, I   was able to fix the error and uninstall the plugin.

If you are looking to fix this issue, here are the steps you need to follow:

Step 1: Use FTP or WordPress inbuilt plugin editor to edit the wp-super-cache/uninstall.php file.

Step 2: Find the text

define( ‘UNINSTALL_WPSUPERCACHE’, ” );

and replace it with

define( ‘UNINSTALL_WPSUPERCACHE’, ‘1’ );

Save the file and try to uninstall the plugin again. It should work this time. Additionally, make sure to follow the other uninstallation notes for WP Super Cache too.
