I am unable to log in to the CUPS interface on Mojave 10.14. I have logged in to this many times with High Sierra and I am sure the user/pass is correct.
Anyone else having this issue?
Can't log in to CUPS web interface on 10.14.
Make sure you have enabled the Web Interface for CUPS. I've just done this on Beta 2 and can confirm it works and I can access the web interface for CUPS.
Open terminal and type sudo cupsctl WebInterface=yes followed by a return. Enter your admin password when prompted. Then open your browser and type localhost:631/printers and press return.
Hope this helps.
