RE:Error: Server Error in '/' Application.
Hi,

This error says that you didn't filled in one or more fields that have to be filled in if you are getting this error in Form tab in CMS Desk. Could you please go to Site Manager -> Development -> Document types -> <document type on which you get this error> -> Edit -> Fields and here please check which fields allow null values (Allow empty value checkbox).

There were several bugs regarding editable regions and page tabs in 3.x versions. This issue therefore may be caused by problem with editable region that occurs under some certain circumstances. Could you please let us know what version of Kentico CMS are you currently using or eventually send us e-mail to support@kentcio.com so we can provide you with hotfix package? Another possible solution to this issue is upgrading to 4.0 version.


Best Regards,
Miroslav Remias
