Thread:Project:Support desk/extension UserAdmin

Hi,

I installed MediaWiki 1.19.0 last week and I want to run the extension UserAdmin. I included the extension and activated it in the LocalSettings.php.  In the Special Pages list I got all the extension function (AddUser, BlockUser, ...) listed, but when I select one, I only get an empty white page ? Did somebody have the same issue or is there maybe a tip what I have forgotten to do ?

Mike
