You shouldn't use "../forum" there, but "/forum" instead, since when you access "/index.php/Main_Page" it's 2 levels deep (being index.php the first level and Main_Page the second) while "/index.php?title=Main_Page" is only one level deep.

If you rewrite those files to start with a slash "/" it will start at the top level, independently of how many folder levels are on the current URL (even if they're "virtual", the browser doesn't know that).
