Breeze Dark is activated, but the theme is not applied.

Firstly, I must apologize for posting this here, because empirical evidence shows that Breeze Dark works for seemingly everyone else, otherwise you would know, I guess. I didn't know where else to post my issue. It probably isn't a bug, but I can't find what I need to do to make it work for me.

Describe the bug My NC instance is still pale and white instead of dark and breezy, even though I have activated Breeze Dark.

To Reproduce Steps to reproduce the behavior:

1. Go to "Apps"
2. Activate Theming
3. Download and install Breeze Dark
4. go to admin settings > theming
5. scroll down to tick all ticks in the Breeze Dark settings
6. Refresh page with Ctrl+F5
7. nothing happens
8. go to personal settings > accessibility
9. tick all the ticks in Breeze Dark
10. Refresh page with Ctrl+F5
11. nothing happens.

Expected behavior NC instance shows different theme: Breeze Dark

Screenshots I don't think those are necessary. None of the site elements are any different than without Breeze Dark. No text is any other shade of grey, no weird lines appear that would show a mixing of themes. No CSS custom theming has been applied in the Breeze Dark CSS customization.

Setup (please complete the following information):

• Nextcloud version: 24.0.4
• Theme version: 24.0.2
• Browser and browser version: Firefox 104.0.1 (64-bit)

Additional context

Settings Overview messages:

• Your installation has no default phone region set. This is required to validate phone numbers in the profile settings without a country code. To allow numbers without a country code, please add "default_phone_region" with the respective ISO 3166-1 code ↗ of the region to your config file.
• No memory cache has been configured. To enhance performance, please configure a memcache, if available. Further information can be found in the documentation ↗.
• The PHP module "imagick" is not enabled although the theming app is. For favicon generation to work correctly, you need to install and enable this module.
• The PHP modules "gmp" and/or "bcmath" are not enabled. If you use WebAuthn passwordless authentication, these modules are required.

Could it have something to do with the missing PHP plugins? Imagick, for instance? Or the memcache? Did I miss another setting somewhere?

Hi!

It's caused by the following setting

This relies on the browser to report if you're using a light or a dark theme and then automatically activate or deactivate the theme based on that. Depending on the exact circumstance of your set up the browser might not be reporting your theme choice correctly, or you may be using a light theme for your system, which causes Nextcloud to stay white.

If you deactivate that setting, Nextcloud will be dark at all times

This did the trick! At least, my suspicion in the OP was correct.
