What is the problem?
I logged out and can't log in. My phone app user name and password work but I can't start a print for some reason from my phone. I can do everything from my phone except start the print.
What did you already try to solve it?
Reboot, Reboot, reboot
Have you tried running in safe mode?
New to Octoprint I don't understand the program languages
Did running in safe mode solve the problem?
serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support! Not log excerpts, complete logs.)
