i got the "The Object Cache add-in file object-cache.php is not a W3 Total Cache drop-in. Remove it or disable Object Caching." message some days ago, hit the "remove" button without any reaction. Today, i clicked "remove" again, which leads to a 500 server error, refreshing brought me a white screen and i cannot access dashboard anymore. website works.
Login leads to a white admin page, but obviously i am logged in, because i can access admin panel in the frontend. But trying to empty any module via the admin panel leads to white page again.
in the wp-content folder, there is no object-cache.php file. Any idea how to solve this? Thanks!
