I just ran the script to upgrade from mv 4 to 5 and it seems ok, after reboot I can't login again in the webui.
I used first aid with ssh to reset the admin password, delete and recreate the sessions folder, add admin user to the
openmediavault-admin group, reset the lockout counter, etc...
I tried everything I found on the net and yet...still get the endless password error on the webui.
Can someone help me please?
