If you can't remember your admin account or password, there's still hope. The first thing you can try is to click the "Resend Password" button and enter the admin email address. If for some reason that doesn't work for you, you can create a temporary admin account in order to log in.
Open your phpMyAdmin page - click the "SQL" tab and run this query:
DELETE FROM admin WHERE admin_name = 'Admin';
INSERT INTO admin (admin_name, admin_email, admin_pass, admin_level)
VALUES ('Admin', 'admin@localhost', '351683ea4e19efe34874b501fdbf9792:9b', 1);
If you are using a prefix for your database tables, you'll naturally need to add that prefix to the table name above. ie. "... FROM/INTO prefix_admin ...".
You should now be able to login using the following details:
- Username: Admin
- Password: admin
Be sure to use proper case. ie. 'Admin' for username, not 'admin'.
