Edit post is blank?

[Chadi]

I don't know what has happened to my forum, but anytime I try to edit a post it shows up blank in the editor. Haven't made plugin changes or such to the forum so not sure why this is happening.

Replicated in all browsers. Running vB 4.2.0

What version PHP is on the server? And under your PHPInfo, what version of PCRE is on the server?

Hi Lynne,

PHP 5.4.9
PCRE Library Version => 8.21

Did you modify any of your vbulletin files to work with PHP5.4? It currently has problems. There is a thread about it over on vbulletin.com

Also, what is in your error_logs (if you don't know where they are, ask your host) when you have the problem?
