I recently changed my password from within WordPress. Today I tried to log in using the new password, but WP wouldn't accept it. The old password doesn't work either. When I use the function to send a lost password, I do get a mail, but when I click the link in the mail, WP says "The e-mail could not be sent.
Possible reason: your host may have disabled the mail() function..."
which may well be true.
What can I do to retrieve or reset my password?
