Thread:Project:Support desk/Unable to Load Extensions (2)

The default extensions installed just fine. But when I try to manually edit the LocalSettings.php to add an extension, the sit will no longer load. If I comment out the extension, the site starts working again. The LocalSettings.php is in the /var/www/mediawiki directory and the extensions are in the /var/www/mediawiki/extensions directory with 755 permissions.
