So you are locked out of your Blesta admin area, the best way to do this is click on the Reset Password url and enter your username to the admin control panel.
If that doesn't work follow the guide below:
Find the following option:
Configure::set("Blesta.auth_legacy_passwords", false); set it as true.
Then go to PHPMyAdmin > Blesta database > users > Edit your username > Set the Password field as function MD5, and put this hash as the value
Your new password will be "password", after you've logged in, change the legacy passwords off, and change your password on My info.
