Hi, just so you know, the DisplayTitle extension has very little to do with the {{DISPLAYTITLE:}} parser function. The extension merely makes it so that links to the page default to the page's display title which may be different from the page's actual title (this is changed with the {{DISPLAYTITLE:}} parser function. In order to have the parser function work, go to Special:ManageWiki/settings, and in the Parser functions section, make sure that the option "Allow Display Title" is enabled, and that "Restrict Display Title" is disabled.
