WSOD for logged users after upgrading some module
go into you database, set the status to 0 on the rows for each of the modules you mentioned. Reinstall each module one by one to find the problem module.  

you could also try adding this to the top of index.php (remember to remove it later)

ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(-1);
