Styling the Wiki

I was on the live support call yesterday and was advised that if I wanted to use my theme’s page template for the Wiki, I should just rename the page.php template to incsub_wiki.php. That did not work. This topic has been brought up by another member in the forum before with no resolution.

I’ve tried this with the WP TwentyEleven theme as well. Only the contents of the main wiki, title and comments show up. The actual tabs, etc have disappeared. Could you please provide a solution to this? If you can replicate a working setup using TwentyEleven, then so should I. Thank you!
