One day my forum has stopped to work. All it says - Warning [2] Invalid argument supplied for foreach(). All the forums and threads are disappeared, but still present in the database. I can't even login to admin page with a second admin account, only with the first one. There are no errors in the web server's log. I've tried to disable all the plugins, but nothing has been changed. I've tried to check for corrupted files. And I've tried to rebuild all the caches (in Tools & Maintenance > Cache Manager > Rebuild & Reload All).
Function cache_forums() returns nothing.
