I just noticed the 'Ask A Question' page doesn't work.
Error:
Microsoft OLE DB Provider for ODBC Drivers error '80040e14'
[Microsoft][ODBC SQL Server Driver][SQL Server]Cannot insert the value NULL into column 'ssdenyid', table 'xxxdbnamexxx.dbo.multibuyblock'; column does not allow nulls. INSERT fails.
The column ssdenyid in the multibuyblock table should have the "IDENTITY" attribute which is where an index is automatically assigned when a row is added to the table. As it seems to have lost the IDENTITY attribute, nothing is added to that column (NULL) when adding a row so the DB is complaining. Is this something you or your host can fix?
