I notice that even when I'm logged out, if I vist url/?preset= whatever it will switch it for the entire site and the user will see the site like that from then on. Can this be turned off? I guess I would just hide that string for my users and if they happen to type that in...oh well...bye bye website colors I chose.
Thank you. Just what I needed. I want to stay in control of my custom style/branding and want to be able to prevent "smart" users from switching styles. I was about to start digging around the code myself, and then I found your post.
