What really mean Unable send email contact administrator ? please help..

Answer 1

If you are seeing that message, it means that your code to send the email is properly going through all the way to the sending of the mail. It's either Drupal or your server that is unable to send the mail after that point. Do you have a mail server on your server? If not, then try downloading the SMTP module, and using a remote mail server (gmail for example).
