Thread:Project:Support desk/MediaWiki and Debian (squeeze)

My server:
 * Debian Linux 6.0 (Squeeze) Webserver.
 * MediaWiki 1.17.0 (Version 95135)
 * PHP 5.3.3-7+squeeze3 (apache2handler)
 * MySQL 5.1.49-3

my problem: I used some JS-Scripts like Collapsible elements and some other stuff. All Scripts works fine and correct, but not on a Debian Linux Webserver. I tryd the Scripts on a OpenSuse and Ubuntu Webserver and the Skripts works. On a Debian Server, not. I don't know why... Need i a special Configuration on my Debian or a plugin/modul or whatever else to fix this problem? Have someone an idea?
