What is the problem?
Can't login to Octoprint website or FTP.
What did you already try to solve it?
I tried that.... I'm still presented with a login username/password afterwards....
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware,
serial.log or output on terminal tab, ...)
It was working with no issues the last time I used it.
So you re-enabled first run. Does it give you the wizard? How did you edit it?
Some screenshots or text of your process would help.
