Thread:Extension talk:MsCatSelect/Installing problems

Hey!

I´d really like to have this extension on my wiki - but I just can´t get it installed. Followed the steps as described (not my first extension actually) and it just doesn´t show up. Also in special:version there is no hint that the installation worked. :/

I use mediawiki 1.22.2. Is there any compatibility issue?

Regards,

Stephan
