I completed the upgrade to 1.8.1. On the “Upgrade wizard” portion, I’m getting an error:

I stopped and will await a response.

Thank you for the rapid report - we’ve made some changes and are in the process of rebuilding the containers. It will take a few minutes and I will revert when complete.

Unfortunately the easiest way forward is to rollback to your backup and re-upgrade when they are rebuilt. Alternatively, if you don’t have any Display Permissions you can skip that step and continue.

There is currently only one display, so it shouldn’t be an issue.

OK sure - it is safe to skip that step then and reapply any permissions you had on that display manually.
