You are not using phpBB3, aren't you?
If you are using phpBB2
the right location for this 'request' would be somewhere here: http://www.phpbb.com/community/viewforum.php?f=48
And if you are using phpBB3
, then you won't get any concrete help regarding this software and modding yet, because it is still in it's beta-phase.
And your problem is style-related I think.
