Method 1:
Goto your website and register as a new user
* make sure to remember the username and password we will need this later!
Login to your database and locate the “Users” table.
Copy the information in the password cell for the new user you created.
Paste the password you copied into the password field of the host or admin account needing the password reset.
Delete the user the user you created in Step 1.
Save the table.
You should be able to login with the host or admin account with the new password you created during the registration process.
If you are still unable to login then try the next method.
