I have the same exact issue. Dashboard blinks for a second and then goes away. I deleted all the files and directories related to this plugin, modified the .htaccess file. If you check out the source code of any dashboard page via clicking ctrl+u, you’ll see
Warning! WP Super Cache caching was broken but has been fixed! The script advanced-cache.php could not load wp-cache-phase1.php. The file /wp-content/advanced-cache.php has been recreated and WPCACHEHOME fixed in your wp-config.php. Reload to hide this message.
Whatever i do, i cannot remove this plugin’s leftovers. Any advice?
