I have been using vb 3.5 since RC1 and have always faithfully upgraded to the next RC (and finally gold!) as soon as they were released. However, about after I added YPN some of my users (a very small amount) began complaining about blank pages after they posted a quick reply. All of the users that have experienced this use FireFox. Coincedence? Maybe. Has anyone else had this experience? If this continues I will post on VB, but at the moment I have not been able to reproduce it whatsoever.
I didn't. However, I found that by removing the YPN ads from the AJAX quick reply (In the postbit template I use: AND !$vbulletin->GPC['ajax'] ) The problem has gone away for my users that had previously experienced it.
