Hi there, no need to panic at all. All you need to do is go to config/blesta.php

Find: Configure::set("Blesta.auth_legacy_passwords", false);

Set it to true: Configure::set("Blesta.auth_legacy_passwords", true);

What this does is allow you to use the old passwords and we use it for WHMCS migrations as-well because of their special hashing.

After you go to your Blesta database and go to the users table for your staff user and change the password to: 5f4dcc3b5aa765d61d8327deb882cf99

You will be able to log in with the password password.

When you've got in, change the legacy_passwords back to false and save the file. Then go to My Info > New password: enter your new password then enter password as the current password and save.

You will have access back to your admin area.
