Merged the fix now, it took a while longer because I needed to figure out how to test it:

This commit fixes an issue in multi-process setups where the following would ha…ppen: 1. Admin changes a theme site setting. The new value is stored in memory in the process that made the change. For this example, changing `enable_welcome_banner` from `true` to `false` 2. Another user visits the site and hits another process, which has the old value of `enable_welcome_banner` still set to `true` in memory 3. The other user's value for `enable_welcome_banner` is cached in the cache for theme site settings, which is shared across all processes The issue is fixed by doing the same thing as site settings: when the new value is saved, we send a MessageBus message to all processes via `SiteSettingExtension` which calls `refresh!` and reloads the in-memory cache of theme site settings from the DB. c.f. https://meta.discourse.org/t/difficulty-understanding-the-enable-welcome-banner-setting/377321

I will deploy your site soon Moin.

Edit: Fix has been deployed
