I think it will give the error, which you see in the first post (PHP Fatal error: Class 'ResourceLoaderLanguageNamesModule' not found in /home/comptf/public_html/includes/resourceloader/ResourceLoader.php on line 437). That's why i would like to know, which module is the problem by adding the lines to ResourceLoader.php and open the url, which gives the 500 internal error :)
