FYI
Many times that type of error is due to a field has blank (empty) carriage returns that can be corrected by just simply.
Going to the end of the entries and deleting the blank white space following the entries.

The same is true for custom islands.

Also you may get a error when processing a cp change and it may have nothing to do with the field you changed but some other field in the form you never touched.
But it will be identified with a red border if it needs to be addressed.

Especially if you change some permissions mid stream after opening your forum.
For example if you added a required profile field and the old user you are updating say a email it will bark because the new required field is blank even though the email is valid..
