@burnout426 said in How to undo "exclude from dark mode"?:
Goto the URL
opera://about, take note of the "profile" path, and close Opera.
In the profile folder, edit the "Preferences" file with a JSON viewer (JSONedit in tree mode for Windows or Geany for Linux maybe). Under root/profile/content_settings/force_dark_mode, make sure there are no entries for any sites. An easy way to do that is to just delete the whole force_dark_mode node. Then, save your changes.
The force_dark_mode list should just reflect what's at the URL
opera://settings/content/forceDarkMode, but mabye there's an entry stuck in the preferences file.
There was one site, deleted, nothing changed.
If you use Opera Sync, log out of sync before you shut down
No Opera sync.
Thx in advance for your help.
