XF 1.5 Can't set default theme.


Active member
I just purchased a theme and put up the logo and everything, however, each time I follow the instructions here https://xenforo.com/help/styles/ where it say I just have to click on the button to set a theme default and it will be safed it does not!

What to do to make the new theme default?

Also even if I'm not loogen in and use a different browser the "theme chooser" below the site is visible, can this be disabled?
