I get a datbase error when trying to use your front end version. I am pretty sure it got an error the first time around when attempting to use the front end version.
I had the regular versions installed, but never added the links. And I was using v1.07 from the start.
No I am very confident it is the staff titles hack, because everything was working fine untill I altered that query. I KNEW I should of made a datbase back up!
