Upgrade from 8.5.9 to 8.9.1 Break

I had another admin user upgrade to 8.9.1 and now I get the following error: Concrete\Core\Permission\Key\MarketplaceKey does not exist

I’m at the point where I cannot even login. Please, any information that gets me up and running again is appreciated!

Hi @edsaxmoore - hmm wondering if you updated to version 9 - maybe 9.1.3? I imagine it’s not easy to tell if all you can see is an error, but the error might include the current version.

In the short term, wondering if you have a database backup available - you can always roll back the database and get the 8.5.9 core files back in place. That’s what I would recommend.
