It looks like that's caused by a problem with your glowhost spam-o-matic installation. If you have it installed, then for some reason you have a column missing from the usergroup table. You can either try to add it back, or uninstall the product and reinstall it if you still want it.
If you have uninstalled it, then for some reason it seems that you still have a plugin from it. Maybe check the plugin manager and if you see it there you could try disabling or deleting it.
