Quote:My hosting account has resent me my login and password
You hosting account credentials have of course nothing to do with your Zenphoto login credentials.
If captcha reset does not work by not getting an email, you maybe did not enter an valid e-mail address on your Zenphoto user account or Zenphoto is not setup to mail (there are plugins).
In this case you need to delete a table in your database. Please see the user guide's troubleshooting on how to reset the password if you don't know it anymore.
