Description:
After upgrading a linux-webserver from

  • MySQL Version from 4.1.x to "MySQL-5.0.30-Debian_1~bpo.1"
  • PHP updated from 5.? to 5.2.0-7~bpo.1

MediaWiki returns empty pages (0 Byte HTML are returned). update.php or re-run
webinstaller doesnt help.

  • In firefox you get an completly empty page (like typing "URL" about:blank )
  • IE7 showes an error-message: "Die Webseite kann nicht angezeigt werden."

(freely translated: "The website cant be displayed").

While searching for a solution, I get contact to five other users with the same
problem.
Only DOWNGRADE to MediaWiki 1.7.1 helps to fix the problem.

I'm using r18669 on PHP 5.2.0, MySQL 5.0.24a without any problem.

I have raised the issu at mediawiki (support page) and I have gotten no anwser

yet.

Your web server is crashing. Check web server's logs and remove third-party
PHP or Zend extensions until you find the culprit.

Bug was fixed within the 1.9-trunk.
Well done!

Quote from Release-notes (1.9-rc1):

Zend Optimizer

A bug in some versions of PHP 5 and Zend Optimizer which was triggered under
MediaWiki 1.8.x has been worked around by disabling some internal debugging
features when Zend Optimizer is loaded. This should solve some common
"blank page" problems.
