What is the problem?
After upgrade to 1.5.1 I cannot get to the UI.. I can still connect with OctoPod, see camera, home, etc.. but if logging to the UI it gets stuck on "Connecting to Octoprint Server".. tried adding /recovery/ and I get "Server Error".
What did you already try to solve it?
Looked at the log, but not savy enough to understand the issue.
Have you tried running in safe mode and if so did it solve the issue?
Tied editing the config to get into Safe Mode, but see no difference. (except startOnceInSAfeMode line disappears after booting as I guess it should)
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.)
