Hi all, I've updated php to 5.3.4 via easyapache and run latest PHP now with apache 2.2, my wordpress sites and old vbulletin forum are okay but xenforo is throwing back 500 internal server error, the only page I can access is index.php?upgrade/ but clicking login returns the error. Mod rewrite is okay on the other sites also. I have suphp enabled for php5 as the handler but wordpress is running cache folders etc with 777 permissions and I cant see why xenforo would only have the permission issue. I've tried rewrite base /, /forum, /public_html/forum etc with no luck. Anyone see or thing of a reason this would happen? php.ini or httpd.conf settings?
