Blank Pages (whole site and admin) after upgrade to PHP 4.4.2

I’ve searched the forums, and tried some of the things others have done to fix the blank pages issue. Last night my host upgraded from PHP 4.4.0 to 4.4.2. This is a dedicated server, and it was at my request (SugarCRM was needed on another site and required the upgrade). Upgrade went fine, and all of my sites and apps are working – except two of them that are of course running WordPress. Both sites were fine before the upgrade, and now all the pages, including the admin pages are coming up blank.

Here’s some relevant info about my environment:

Red Hat Entrprise 3

MySQL 4.1.12

As far as I can tell nothing changed except the PHP version. I host at rackspace and have them looking into it. But wanted to throw it out to the WP community and see if anyone’s run into this before. The other blank page posts in the forums didn’t reveal much info. I have shell access to the server, so there’s not much I can’t do or have done to help debug this issue.

Thanks for all your help in advance!
