Alright Chuck I've got a question for you.
I am using a tab mod in vbulletin, and I am trying to figure out how to keep the tab highlighted as "active" when I am in PhotoPost. In order to do this, the php file name and the THIS_SCRIPT value needs to match.
On my site, the default vBulletin forum THIS_SCRIPT value is "index". Photopost default THIS_SCRIPT value is "ppindex" - so that is fine.
However the default vBulletin php index is "index.php" while the default PhotoPost index is "index.php" as well. What I really want to do is change the PhotoPost php to "ppindex.php".
If I do this, will I break everything? How much manually editing will this entail>?
EDIT LOL I'm a stud

I just put up a duplicate "ppindex.php" file in the same directory as my default "index.php" for PhotoPost - an exact copy. Then I pointed my navigation at ppindex.php and everything works like a charm!
