Hi,

I'm getting an error just when trying to place the forum module on a page.  This is on DNN 5.6.7 using Forum 5.0.2.  Any insights would be helpful.  The error is:

InnerException: Cannot insert the value NULL into column 'EnableModNotification', table 'databasename.dbo.Rel_Forum_Users'; column does not allow nulls. INSERT fails. The statement has been terminated.
