This is the instuctions I got. So where do I go in wordpress to do them, it doesn’t say:
Open your browser and load wp-content/plugins/wp-super-cache/uninstall.php directly. You must be logged in, and you must confirm the action. If you do not delete the plugin immediately, after the script runs, please comment out the define() above to stop someone else running it.
To manually uninstall:
1.Remove the WP_CACHE define from wp-config.php. It looks like define( ‘WP_CACHE’, true );
2.Clear the cache in the backend page and then deactivate the plugin on the plugins page.
3.Remove the Super Cache mod_rewrite rules from your .htaccess file.
4.Remove the files wp-content/advanced-cache.php and wp-content/wp-cache-config.php
5.Remove the directory wp-content/cache/
6.Remove the directory wp-super-cache from your plugins directory.
