You need to edit 'overall_header.tpl' for the default style on your forum, and NOT 'bbcode.tpl'
It's not the years honey, it's the mileage...
I do not provide any install services for phpBB, Mods or Styles.
Please do not pm me for support/scripting help - you won't get any reply. If you have a question then make a post in the appropriate forum.
