Trixbox config repair and harden down

So I was trying to "harden" my trixbox system from a tutorial by changing passwords/users in [login to view URL] and changed passwords in the mysql database. When I tried to fix it after that mistake it all loads the main stuff but when I click on PBX settings it constantly asks for authentication now to no avail. I would like someone to repair this for me and also while they are inside, if they could secure the box as well from penetration and securing trixbox.
