Disallowed Key Characters when debugging

its weird your getting the error, i received the error before but when i used ?> at the end of a file, my own fault for diving in before reading how it works lol.

have you changed the permitted characters in your config file?

$config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-';
