Thread:Project:Support desk/Diff not showing in MW 1.23/reply (3)

Ok, found the issue. The extension was enabled through the /etc/mediawiki-extensions/extensions-enabled symlink file.

I did an upgrade from MW 1.19 to 1.23 and the 1.19 version was from apt-get repository. I guess that was the remnant from that install. I think I'll stick to manual install next time...
