problem while uploading

[JerCo]

When I upload some files, I always have an error like this :

Warning: getmypid, dl, leak, listen, chown, chmod, chgrp, realpath, tmpfile, link, mb_send_mail() has been disabled for security reasons in /data/members/free/tripod/nl/h/p/p/hppatronus/htdocs/upload.php on line 1186

What can I do to solve that problem?
