Topic on Extension talk:UserAdmin

Going to purge user, I enter a username ("1t6a0t19942") and hit search.

This takes me to the following URL;

http://www.liblfds.org/mediawiki/index.php?username=1t6a0t19942

Which simply shows the root wiki page.

Total fail. Third extension I've tried to obtain the capability to mass delete spam users, not a one of them works.

It really doesn't seem to be working on 1.19: I'm also getting redirected to the main page of my wiki.
