I'm quite certain the error I'm getting (see below) arises from a packaging problem in Debian, i.e. Debian package 'mediawiki' (1:1.12.0-2lenny2) is not compatible with 'mediawiki-extensions' (1.4), as mediawiki-extensions (1.4) appears to be derived from extension in the 1.13 branch of mediawiki.

This is most likely not going to work well if at all.

Mediawiki is a fairly new addition to Debian, so you may want to converse with the package maintainer.

Not worth the effort. In my opinion your better off 'rolling your own'!

You may need to check to see that your php settings are compatible with the mediawiki you are using.

A word of advice: only enable the extensions NEEDED and then only one at a time. They are much easier to debug if you do that.

Lastly: top posting is frowned upon within this list:
Good luck!
