I am getting the following error as an Admin and as user
Microsoft OLE DB Provider for ODBC Drivers error '80040e14'
[Microsoft][ODBC SQL Server Driver][SQL Server]Cannot insert the value NULL into column 'TOPIC_ID', table '801167_default.dbo.FORUM_TOPICS'; column does not allow nulls. INSERT fails.
well, you need to find out what has changed, the topic table can not suddenly loose its autoid field without someone editing the database to change it, if it doesn't have an autoid the only explanation I know of is that you upsized an access db rather than using the forums setup.asp
The database field 'TOPIC_ID' in the database table 'FORUM_TOPICS' supposed to automatically generate a number when you make a new post. But either you or your host, made some changes to the Snitz database and has caused this problem.
Did you make any changes to your database recently? Or did your host make any changes recently?
