Wordpress Issue

Please read fully before sending a PM. This is an EASY project for those who know what they are doing. One of our sites: [login to view URL] has a section called "whos in the studio" (found on the top navigation bar) and we added a new section "whos that" (under the section "Media" in the top navigation bar). The PHP file associated with "whos in the studio" is page-news.php. The PHP file associated with "whos that" is page-news2.php. In order for us to post them respectively to each page, we initially used "custom post type" to properly direct each ones destination. "whos in the studio" is named "news". "whos that" is named "news2". We went through the "theme functions" and thought we did everything correctly; however, when we click "whos that" it gives us a Server Error. I have tried everything I know, but I can not get it. PM for back end details. Need this done ASAP!
