I just upgraded from EE 2.2.2 to the latest version. Now when I go to edit or publish an entry in a certain channel I get a blank white screen. The other two channels appear to work fine.
How can I debug this? What would be different about that channel to make it stop working? The only think I can think of is that the channel uses a custom fieldtype that is breaking it?
Urgent help appreciated. I can provide admin login if required.
Thanks,
Benek
