I just upgraded my FreeNAS to TrueNAS from 11.3 to 12.0.
The upgrade itself went without issue but the HTTP webinterface still shows the FreeNAS interface (with most buttons not working). HTTPS shows the TrueNAS interface.
I also get this warning:
System core files were found in /var/db/system/cores. Please create a ticket at https://jira.ixsystems.com/ and remove these files.
The file in that directory is "su.core".
What should I do to fix both issues?
