You're item DB is out of date probably. New columns get added to it a lot with new versions. Try making sure you download a DB that says its compatible with the version of the server you have, if thats not possible you need to download the apropriate item mod sql files from
http://cvs.biosprite.net/ to convert from the version you have. These files are for people who know what they are doing so if you can't figure out what you need there really isn't any support for them, so jsut find a more recent DB.
