Fatal error: Call to a member function add_global_groups() on a non-object in ..

  • Hello I just upadate some plugins and after that I get this error
    Fatal error: Call to a member function add_global_groups() on a non-object in /home/xxxxx/public_html/wp-content/object-cache.php on line 14

    the only way to visit my site again is to delete the object-cache.php

    I also tried to disable all plugins but with no results…any ideas?

    Have you tried:
    – deactivating ALL (yes all) plugins temporarily to see if this resolves the problem (plugin functions can interfere). If this works, re-activate them individually (one-by-one) to find the problematic plugin(s).
    – resetting the plugins folder by FTP. Sometimes, an apparently inactive plugin can still cause problems. Also remember to deactivate any plugins in the mu-plugins folder (if you have created such folder). The easiest way is to rename that folder to mu-plugins-old.
    – switching to the unedited default Theme (Twenty Sixteen) for a moment using the WP dashboard to rule out any theme-specific issue (theme functions can interfere like plugins).
