Sounds like that error message should be changed to include what face causes trouble, if possible? BTW here is a function to loop thru all faces and set them to something, try for example ;; (set-all-faces "red") Maybe you can modify that to retrieve attributes instead? That could be cool ... (defun set-all-faces (fg &optional bg weight) (let ((backg (or bg "black")) (wght (or weight 'normal)) (faces) ) (mapatoms (lambda (s) (when (facep s) (push (symbol-name s) faces) ))) (dolist (f faces) (set-face-attribute (intern f) nil :foreground fg) :background backg :weight wght :italic nil) )) -- underground experts united https://dataswamp.org/~incal
