OK - I've installed pp5.3 and my users are able to access the gallery by following a link and they don't have to log in again. That's all good. So no I'm trying for full integration as per Michael P's instructions
here.
The trouble is I get SQL errors in
vB when it's looking for inc_features.php and inc_photopost.php indicating that they can't be found.
Both files exist in public_html/photopost and the vBulletin index.php file is in public_html/vbulletin. So adding the lines:
include('./photopost/inc_features.php');
include('./photopost/inc_photopost.php');
should work but don't. Am I missing something obvious here
