According to http://kb.mozillazine.org/Special:Version your server is seriously out of date:
MediaWiki 1.6.8 (not even the newest version of that branch, but 1.6 was EOL'd in early 2009)
PHP 4.4 (EOL'd in August of 2008)
MySQL 4.1.15 (EOL as of the end of 2009).
Why are you using such ancient and insecure software still?
