As of yesterday’s update (of my hosted server at https://doomemacs.discourse.group), none of my custom CSS is applied. Changes to my theme(s) or components’ CSS have no effect (though changes their or other HTML sections work fine). There is one suspect link tag pointing to an empty stylesheet, whose hash changes each time I change my CSS. It appears Discourse is silently failing to compile my stylesheets. There are no mentions of failures in my error logs and discourse_theme uploads my stylesheets without complaint, but to no effect. Would an admin kindly have a look?

The fix is now merged in core and your site is deployed @hlissner. Note that I disabled two theme components: the one with custom styles (which you can enable) and discourse-theme-category-homepage, which needs to be updated upstream before you can enable it.

~~I am not certain, but I think you might be hitting this change https://meta.discourse.org/t/restrict-editing-of-remote-themes/170051~~ Looks like this is incorrect :smiley:

Thank you! The stylesheets now correctly load, however, the SCSS color variables don’t appear to inherit my theme’s color scheme. e.g. $secondary yields its default value, #ffffff, instead of #282c34. Is this perhaps another regression from e8b8272?

Yes, it is another regression. It’s a bit of a tricky fix… and for the vast majority of color variables, theme components should be using CSS custom properties. You can look at this guide Update themes and plugins to support automatic dark mode, for an overview and some examples on how to add custom color variations in a special color_definitions.scss file in your theme component. Let me know how it goes!

I’ve done so where I can, but without access to these variables I cannot transform colors based off my active scheme. e.g. $primary-low: dark-light-choose(darken($secondary, 12%), lighten($secondary, 10%)); :root { --primary-low: #{$primary-low}; } Is there a better way around this? I could add styles directly to each theme, but I intend to have many, and I’d rather handle some general cases from a central, global component where possible.

Yes, that makes sense, did you try adding that SCSS above to a new file in common/color_definitions.scss? It should just work if you add it there. (There is also a tab in the UI for that special stylesheet.)

Was about to try exactly that, then the discourse went down with a The software powering this discussion forum encountered an unexpected problem, haha.

You can access the site via /safe-mode, that disables themes and components and then you can see what happened. This is yet another regression though, those SCSS errors should not blow up the whole site, I’ll certainly fix that in the next few days.

That worked! The color variables are properly set in color_definitions.scss’s scope. Only trouble is I can’t import other stylesheets from it. e.g. // scss/globals.scss $foo: "#000000"; // color_definitions.scss @import "globals"; :root { --foo: #{$foo}; } Yields this in the Discourse error logs: SCSS compilation error: Error: File to import not found or unreadable: globals.scss. on line 129 of color_definitions.scss >> @import "globals"; I can redesign my stylesheets to avoid the dependency though, so not a big deal, but could this be considered a bug?

Yes, I have a PR up to fix the import issue, should be merged by tomorrow. https://github.com/discourse/discourse/pull/11963

Hi @hlissner, I am working on a fix for this, a recent upgrade to core broke the theme component on your instance. I should have a fix shortly.
