Found a weird problem, maybe I just broke something in editor but theme selector doesnt work from home page. But works fine in UCP and in forums. Just not working on home page - reloading and back to the same theme.

I'm using Curves UI, Inspired Dark and standard theme. So weird, from standard theme the selector doesn't work either.

Fixed for all desktop templates, small error in .htaccess.
It also works in responsive mode (Curves UI) but doesn't work at all in responsive mode (Inspired Dark), na matter where I change the theme.
