After install, error on index.php
 

Error:
Warning: main(./global.php) [function.main]: failed to open stream: No such file or directory in /home/xxxx/www/gallery/header-inc.php on line 61

Fatal error: main() [function.require]: Failed opening required './global.php' (include_path='.:/usr/local/share/pear:/usr/local/lib/php') in /home/xxxx/www/gallery/header-inc.php on line 61

I had this problem, are you integrating with a forum? if so check that you have specified each databases in the inital config (i.e not the same information for photopost and vbulletin forum etc)

If your integrating with vb3 on the last step of install the proper server path to the forums was not entered.

In config-int.php edit the file and place the right path to your vbulletin for the $vbpath variable.
