Really do you thing that i go to hidden ALL the wiki?? Really, i need hidden only the lists under the Category page content, I tried to hidden the $r lines but continues appearing the subcategory and article list headers with the number of articles. Thanks
Try commenting out the entire getHTML() method of CategoryPage.php (just the contents of it, you might need the function declaration to stop it crashing). Then you should end up with just the skin and no contents.
