Today when i click on the Delete Cache button on Super cache Plugin settings page, my wordpress dashboard goes blank along with whole site. After some investigation, i found that the fault was because of Super cache wordpress plugin and i need to uninstall (complete removal of super cache plugin) and reinstall the Super cache plugin.
Solve Plugin Blank Page problem because of Super cache wordPress plugin:
Take backup first
1.Turn off the caching and deactivate the plugin. If you unable to access your wordpress admin dashboard, just go to wp-content/plugins folder via FTP or your site’s control panel file manager and rename the wp-super-cache folder to .wp-super-cache folder.
2.Then open the wp-config.php file from your wordpress root folder. And remove
define('WP_CACHE', true); //Added by WP-Cache Manager
line and save the file.
3.If you find any Super Cache mod_rewrite rules from your .htaccess file, just delete and save the file.
4.Delete wp-content/advanced-cache.php and wp-content/wp-cache-config.php files from your server.And also Delete wp-content/cache/ and wp-content/plugins/wp-super-cache directories
Now your wordpress site will work. Just install the Super cache wordPress Plugin again and activate it. It will solve the problem.
Thank you very much! This article helped me when WordPress site and admin dashboard were unaccessible!
