Request a new password mail without any content inside of the mail. I got a problem. When I want to request a new password due to password forgotten, the system definitely send a mail to my email address. But, this mail is without any content inside. 
I check the Configuration->People->Accounting Settings. I already setup all the content. But, I can't get any content. 
Hope someone can help me. Thanks.
