The above exception was the direct cause of the following exception:

@Mailstorm-ctrl it looks like you are upgrading directly from 3.6.3 to 4? You need to first upgrade to the most recent minor release (v3.7.8) and then upgrade to v4, otherwise there can be issues. Please see (https://docs.netbox.dev/en/stable/installation/upgrading/) Please let us know if this resolves the issue.

So I got upgraded to 4.0.1 withouth migration issues but now I'm pretty confused on what happened with my install.

When I first set netbox up I did logging for LDAP because it wasn't working. I guess I never turned it off (oops). When I now start the netbox service see the following error:

I thought I could just make the file and it'd be dandie but it's still acting like it isn't there. And what's really confusing me is why the traceback is referring to netbox 3.6.0
