We apologize for the instability of composr.app and appreciate your patience. We are working on the statistics addon and trying to find an optimal way to store and render data. Unfortunately, we have yet to find a solution that can handle the traffic (and therefore, tens of millions of statistical records) of composr.app. We're working hard on one.
First, big apologies that it asked you to upgrade to a beta! Especially a beta of a line that we've discontinued (we're going straight to v11).
This is now fixed, and I've added more automated testing to the versioning system.
As for this specific error, it looks like files for the ecommerce addon came back, which you'd uninstalled. So files, but no DB tables. I would guess this was caused by manually extracting the upgrade, or it already having a rogue addon_registry hook for that addon and it restoring the rest of the files. We're aiming to make this a problem of the past with v11 as it happens to too many people.
