Hello there, I'm trying to get this to work on mediawiki version 1.16.4. I am having issues with the tabs showing up. They come out as bulleted text instead of tabs. I have read around about possible solutions but there are not working for me, I've installed yui 2.8, used Header Tabs version 8.3, 6.6, 7.0 to no avail and I'm basically stuck. Any help or guidance would be greatly appreciated. Thank you.
