Errors after deleting plugin

This is the error message I receive when I try to add other plugins:

define(‘WP_CACHE’, true); //Added by WP-Cache Manager define( ‘WPCACHEHOME’, ‘/home/content/12/12111512/html/dselive/wp-content/plugins/wp-super-cache/’ ); //Added by WP-Cache Manager

Indeed, caching is very likely to interfere with other plugins, no matter which caching plugin you use. That’s by nature.

Before cursing the caching plugin (any caching plugin), I would test if maybe one of your already installed plugins is not playing nicely.

Just a thought.

The uninstall guidance for super-cache is as follows:

1. Turn off caching on the plugin settings page and clear the cache.
2. Deactivate the plugin on the plugins page.
3. Remove the WP_CACHE define from wp-config.php. It looks like define( ‘WP_CACHE’, true );
4. Remove the Super Cache mod_rewrite rules from your .htaccess file.
5. Remove the files wp-content/advanced-cache.php and wp-content/wp-cache-config.php
6. Remove the directory wp-content/cache/
7. Remove the directory wp-super-cache from your plugins directory.

I would work through steps 3-7, and create backups of your wp-config.php & .htaccess files before removing the super-cache code.

This should solve your issue.
