I purchased the gallery a few days ago and just installed it on my main site, which is separate from my forum, although both are on the same server. (forum has its own subdomain).
At first the gallery gave me a blank page, then I added the full path to the two requires below:
require_once('./global.php');
require_once('./includes/functions_gallery.php');
in the gallery_global.php and the gallery is now working.
Is that the only place I need to put the full path to those two files for the gallery to work? Just want to make sure...
PS: Some of the images don't show up though for my main style, like the /images/misc/ images and images from the /images/buttons/ but I fixed this easily by editing the stylevars images paths for the forum style to use full URL. had this problem for the local install of the gallery too. The images showed up ok for my other styles.
