Hi all,
After I update my Kentico from 7 to 8 then 8 to 8.1, I can not save content after I updated. I got error:
An error occurred when saving data. Please see event log for more details.
Message: Object reference not set to an instance of an object.
Exception type: System.NullReferenceException
Stack Trace:
at CMS.Controls.CMSEditableRegion.IsValid()
at CMS.PortalControls.CMSPortalManager.Validate()
at CMS.PortalControls.CMSPortalManager.DocumentManager_OnValidateData(Object sender, DocumentManagerEventArgs e)
at CMS.FormControls.CMSAbstractManager`2.RaiseValidateData(EventArgsType args)
at CMS.FormControls.CMSDocumentManager.SaveDocumentInternal(String actionContext)
I figure out a topic mentioned about this error and "Juraj Ondrus" said "It will be fixed in the hotfix 8.1.1". So please suggest for me a best solution.
