Just upgraded to PP 7.03 under vBulletin 4.0.8 pl2. I didn't notice any upgrade problems but some photo subdirectories are not displaying properly under Firefox 3.6.3 but there are no problems with Internet Explorer or Chrome.
Please check out this problem URL
I cleared the Firefox browser cache and all cookies to see if that was a problem, but that had no effect.
Thanks. -- Rik
