Thanks a million!
That one line of code is gonna save me so much trouble.
It basically was a problem of my mysql user not having the 'create' and 'alter' privileges. Once I had those I was set!
Hi - real rookie question I know... I'm trying to do the same thing for a custom theme I've made. It's called loco3. Where do I put the php to make the extra field? I know themes shouldn't contain any php.
