Recently, I cannot change the theme of my account on gitlab.com. I decided to give the “Dark mode” theme a go, and have since decided I want to switch back. However, if I try to make any changes in the Navigation Theme or Syntax Highlighting Theme sections of the Preferences dialog I am presented with an error “422: The change you requested was rejected.”
It appears that other changes in the Preferences page are processed properly. It’s just the “Navigation Theme and Syntax Highlighting theme” radio buttons.
I have tried this with both Firefox and Chrome with all browser extensions disabled, and also in Incognito/Private modes. I’m at a loss of what to try next.
I have seen may other posts regarding error 422, however few of them seem to be regarding privately hosted repositories, and not gitlab.com proper.
Thank you in advance!
