The photon UI under photon.lemmy.world does not work for me in Firefox 122 under Linux, showing nothing but blank page when I open it. It works in Chromium and in Firefox on Android.
When I open the developer console, I get the following error message:
Uncaught (in promise) TypeError: e.moderation is undefined
Hey, that actually did it! Not cookies, technically, but “local storage”, but anyway…
Thanks for the hint!
*edit: In retrospect, I should have saved what Photon had saved there in local storage. This was definitely still a bug, Photon, like any other web application, really, must be able to deal with data stored by older versions of itself, even if those older versions were buggy.
