@meiso-op said in Dark theme in pages is forced even when not selected.:
Or you can call the view of the 'element code', then close and the page becomes normal.
exactly same for me , black pages ,if i inspect element and close the pop up box from it the black background goes and it returns to how it should be
latest build of windows , no extensions installed on opera GX either , tried reinstalling the browser ,clearing cache and other things suggested here nothing works aside from the inspect element and close
