Made mistake of listening to some warning about needing to make root password more secure. Should have left well enough alone. After changing password, could not log in using the new password.

Finally used procedure for lost password in Manual Troubleshooting page

Delete these files:

config/passwd

config/shadow

config/smbpasswd

 

After putting the flash drive back in and starting up: unraid boots, Plex runs and I suppose it's checking parity since I could not shut down cleanly with logging in after the password change. But, I can still not log in. The Troubleshooting page says all passwords are set to null by deleting the config files. But unraid at first said I needed a password and I now keep getting the error shown below.

I still have copies of the config files I deleted. 

 

Help please.  

 

While I'm asking, have backed up the flash drive to server on occasion, but have no idea how to recover the backup without logging in.  

 

Never mind, for now anyway.  Following a suggestion, I cleared browser cache.
