Edit wordpress code

Hi, Some minor edits in code are required. The website is built around a premium template and has further been modified. After the latest Wordpress update, some of the CMS side functions are broken but the front end is still fine except for one slider that doesn't rotate the slides as it should. Another problem that occurred after the update is that when logged in, the multilingual versions do not display when clicked, but simply a white screen of death is displayed. When logged out, all is fine. What I need: 1. The edit in code that is needed is actually adding code to the php template file that displays specific pages (posts and portfolio style pages - [login to view URL] and [login to view URL]) to include content written in the post content box, as it is currently not included in the loop. Currently they only show the galleries as that was the only requirement, but now, I need to include content and links as well on the top. 2. Fix the slider on the home page. It displays the first products OK, but when it auto or manually slides it breaks. The website name is glorigb dot com dot mk if you want to see the homepage slider and where it breaks.
