Forum Blank page on showthread.php
 

Upgraded from 3.x.x to 4.2.0 this evening.
thought all was going good, until I went to view a post,
the showthread.php is returning a blankpage, no error, no nothing
I have been through the 'blankpage' doc http://www.vbulletin.com/docs/html/blank_pages
this is on php 5.4.11 so I hope the 5.3.5 bug doesn't apply

anybody got any idea's ??
