Theme is not working anymore in RStudio 2021.09.2

[antonj19]

Issue:
The preview in RStudio is just black text with background and after applying the theme every window has got dark grey background with black text.

Steps to reproduce:

1. Download night-owlish.rstheme
2. Add it in RStudio 2021.09.2: Options > Appearance > Editor theme > Add...
3. Choose Night Owl

I'm really sorry, but I can't reproduce this on my machine. Hopefully someone else runs into this issue and has a fix for you.

Do other custom themes work for you?

The rsthemes package has a bunch of RStudio themes (including a version of Night Owl) and uses a different installation process, so maybe check that out.

🤔 I am definitely curious, though, if the problem you're having is specific to this specific theme versus any other custom rsthemes you've installed.

Thank you!
The installation of rsthemes solved the issue. I can now choose "Night Owl {rsthemes}" in the editor theme settings.

I don't know why the other way didn't work this time for me (it did work in my previous RStudio installation).

Glad to hear it! I'll leave this issue open, since we haven't actually fixed the source of your problem.

Exactly the same issue for me. When installing from the provided .rstheme, the preview shows black on white, and after applying all the windows are black on dark gray. Running RStudio 2023.12.0 on Windows 11.

Likewise, installing rsthemes allowed me to select "Night Owl (rsthemes)" and it worked correctly.

Edit: While doing other work, I got this console error message regarding the original Night Owl theme (not the one from rsthemes):

Warning message:
