Support » Fixing WordPress » 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:

    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!

  • When a request to a WordPress page is made it actually causes the apache child process to segfault, which is why a blank page is returned. I would recommend that we go ahead and down grade to PHP 4.4.0 to ensure this isn’t an issue with this particular PHP build.

    This is what Rackspace has found out so far. I’ll let you know if we find a solution.

    Now rackspace is saying that WordPress has problems with PHP 4.4.2 – can anyone confirm that?

    Same exact thing is happening with my host Javapipe. They can’t figure out why this is happening but they did upgrade to 4.4.1 (as well as to a new server os called CentOS or something like that. My wordpress site is completely down now and I am getting no help anywhere!

    (posted my support request on here yesterday with no replies…)

    Rolled back to PHP 4.4.0 – All is well and wordpress is back up. And because SugarCRM 4.2 was installed while in 4.4.2 (the install would stop because 4.4.0 is an unsupported version), it is still running and is functional. It could blow up, but we’ll see.

    Just wanted to update the thread for the next blank pages searcher.

    Having same problem. Any idea on a fix?

    Same problem here, is there a way to get it fixed? my website is totally not working anymore: PHP 4.4.2 WP 2.0.2

    please WP-community, help us out on this matter!
