Looking for it for about an hour now. I have two active themes but I don’t know how to switch between them. Maybe it’s some general setting that Users cannot change themes, but I can’t find that either.
AI-generated summary
A user pyc installed and enabled two themes but couldn’t find how to switch between them in user preferences. Heliosurge pointed to the Preferences > Interface section and shared a screenshot showing where theme options appear, including a sidebar toggle. Moin asked if the setting “Theme can be selected by users” was enabled for both themes — which pyc confirmed — yet still saw no theme dropdown. After logging out and back in, pyc found the theme option appeared, suggesting a cache or session refresh issue. Moin noted they’ve never needed to log out — a simple page refresh (Ctrl+R) usually suffices — which pyc agreed might have been enough. The issue was resolved by refreshing the page or re-authenticating, highlighting that theme visibility in user preferences depends on both correct theme settings and browser state.

This TC adds a switch to sidebar like here on 
Did you enable Theme can be selected by users for both themes?
Then you should see a dropdown in the interface preferences of your profile. Here at Meta you can select a theme at https://meta.discourse.org/my/preferences/interface
Yes, I enabled both themes to be selectable by users.
And I have no Theme option in Prefereces/Interface ?!
OK. I just logged out and logged in and I now have Theme option. I guess that was the problem, with some changes you need to logout and login I guess?
I’ve never had to log out after changing something. Refreshing the website has always been sufficient.
Maybe that was the case too… CTRL-R was needed at least.
