Resetting A PhpBB Admin Password After An Upgrade

While helping upgrade an old phpBB 2 messageboard to phpBB 3 earlier, I needed to reset the admin password.

I was getting tbe error "It was not possible to convert your password when updating this bulletin board’s software." after I'd converted the old user data and tried to login as the admin user.

To reset the admin password to "password" you have to do the following.

1. Login to your database and look in the phpbb_users table for the admin user.
2. Set the user_password to "$H$9Ae3Uk.ECdWW5ya13M4ErWhr4c.761/", user_login_attempts to "0" and user_pass_convert="0".

You should now be able to login with your admin username and the password "password". Remember to change this once you are in for security!
