"'data' is not a known object store name" [Zen Browser]

Currently using Zen (a Firefox fork) on two different machines. On one, all is well. On another, Zen will not fully render - I see a top bar, but no page title and certainly no page content, and clicking the buttons other than to switch to sync mode does nothing (switching to sync mode doesn’t do anything either).

The error appears in the console as DOMException: IDBDatabase transaction: 'data' is not a known object store name

I have my notes URL under an exception for any of Zen’s enhanced privacy features currently, and I haven’t done anything special on the other machine where it works. I also can’t do any debug steps in SB because I can’t access the command prompt.

Any thoughts what might be causing this?

Strange. When you open the developer tools, under Application can you try to unregister the service worker and reload the page and see if that does anything? If not, clear your browser cache?

I did both, as well as deleting local storage in the developer tools, but that didn’t work. It’s bizarre! I’m going to clear cache again just to be sure.

Damn, that worked, lol. I tried both steps back to back not even 30-45 minutes ago without effect. Thank you, as always.

All this service worker and caching stuff is messy business (two hard problems in computer science). Happy you fixed it.
