Problem with new custom template

[usernamenone]

This error usually means a PHP version incompatibilty issue. Either you have used an older template out of the download section or your server is using an older version.

This is a little odd as the pages_title column has always been a part of the ezpages table. Have you checked the table in your database to make sure that it hasn't been accidentally deleted?

(Personally doubt that this is a PHP compatibility issue as the problem lies between a SQL statement and the database - so there's no PHP involved)
