I don't recall what the version of Koha installed was, and I'm having trouble finding where I can find out what version it is. The upgrade to a later version of the mysql server could be causing the "You have an error in your SQL syntax" problem? It could also be that perl packages were unintentionally removed during the upgrade, or modules originally checked out of CPAN may no longer be working? As a general approach, if I upgrade Koha now to the latest version, would this be a good first step? Cheers, Alex
