I was just trying to create and get this error. Has anyone, had this error or know what it could be related to?

Did you recently upgrade from an older version?  If so, did you remember to restart?

There was a change in v2.11.1 which added natural ordering to virtual machines (_name column), but you appear to be running 2.11.0.  Hence it looks like you're running 2.11.0 code with 2.11.1+ database.

Yes, I upgraded to v2.11.1 and then downgraded to v2.11.0, for what ever reason I don't remember. Do you know how to downgrade database, because I already run migrate, upgrade scripts and restarted netbox, but it do not seem to help.

You can't downgrade, unless you restore your database from a backup taken when you were running v2.11.0 - and obviously you'll lose all changes you've made to the data since then.

Can you describe what problem you saw in v2.11.1 that wasn't in v2.11.0?  I would say it's very likely to have been fixed in v2.11.4.  Check the release notes for v2.11.2, v2.11.3, v2.11.4 for bug fixes.  In any case I suggest you roll forward, not back.

I will try upgrading. I believe problem was with new table view customisation.

Upgrade fixed the problem. Thank you for the help Brian.
