i already updated some 2.3.x to 2.5 which worked well. Today i'm on a bit bigger installation and i'm stuck in wp-admin/upgrade.php - after updating the db it tells me it's finished and i'm getting back to the message that i need ot update my database.
I can hit that 100 times which doesn't change anything. I already rolled back to backup and completely restarted some times - i also reuploaded the files 2 times - nothing changes.
Any idea where i can get some 'more saying' error messages or something to find out where the problem exactly is and so probably find out why and fight it.
