Hi,

From \extended profile\field module, I created a new field ("telephone"). Creation of the new field was successful, but once I register a new member, I got this error message:

You are now registered. However, we were unable to send the activation mail to your email account due to an internal error that had occurred on our server. We are sorry for the inconvenience, please send the webmaster an email notifying him/her of the situation.

Could anyone have an idea about this?

-Thanks.
