I have lost the password to login to my own drupal installation. Sounds silly, but Mozilla remembered it so well for months that now I have forgotten... and Mozilla too.
This wouldn't be a problem if Drupal could send me a new password, but for some reason it can't because this error message appears after introducing my userID in http://desdeamericaconamor.org/blog/en/user/password
Unable to send mail. Please contact the site admin.
Being myself the site admin, what can I do? :/ Also, I have requested previously new passwords and this function worked. This is a Drupal 4.5.1.
