Thread:Project:Support desk/references doesn't work/reply

The problem is that the "ref" tag is not parsed. The content inside it is, but the tag itself is not. I just checked that on a wiki I am running (with MW 1.18) and I have the same situation there.

This is done by the file Cite.php, which is part of the Extension:Cite. It adds "ref"-tags and makes them be rendered as a superscript number with a reference in the reference section.

The solution is to install this extension!
