Thread:Project:Support desk/Failed to open stream: Invalid argument (3)/reply

It's all in the error message: In LocalSettings.php on line 127 you have an error. The path to this extension is somehow wrong. The slash is missing and a "�" also does not belong there.

Make sure to fix the line so that it points to the actual path!

However, the error "unexpected 'require_once'" makes it look like the problem or another problem might also be in one of the lines before line 127. Maybe you have a missing semicolon or so...
