URL file-access error message

Installed JA Submit v2.1 in backend when I try to access 'Read me' I get following error message

Warning: require() [function.require]: URL file-access is disabled in the server configuration in /home/mysite.com/administrator/components/com_ja_submit/admin.ja_submit.php on line 522

Added JA Submit link to User Menu now in front page when I try to access I get this error
