I am running Mediawiki 1.24.1 on a shared hosting Apache environment with Vector Skin enabled. "No Title" works beautifully with native url, but when you activate short URL's per Manual:Short URL/Apachethen "No Title" seems to not like it. This may also be causing your issues with this extension not working properly, or I should say, the extension works as intended, but when you change the URL to short URL's, the extension does not play well with that. Functions properly with http://your_domain/mediawiki/index.php?title=Main_Page Functions poorly with http://your_domain/wiki/Main_Page
