umm thats strange, I made sure to test that password reset is working before releasing Mys v1.3.4. Theres a chance that the admin account is not created properly for you when you installed the script on godaddy(as the admin user email may not be set at all).
Anyway there are easier ways to test whether a functionality of PHP is available on your server. Go to the root index.php file for your adoptables directory, and add the following code right after the php opening tag <?php
PHP Code:
$password = "0123456789abcdef";
echo md5($password);
echo sha1($password);
echo hash("sha512", $password);
See if the script actually outputs these password in a hash format, or that it throws a function not found error.
