I keep getting the dreaded "Forbidden" message when trying to modify my printers. I've read the answer is to log in to CUPS as root, using the localhost:631 address in the address bar.
I'd love to be able to do that, but I am never prompted to log in, and there is no login button anywhere, not even after you click on 'administration'.
I've posted a picture of my screen so you can see for yourself there is just no way for me to log in.
Any help appreciated.
Here is the picture.
