@dannycoates It seems that this issue is also reproducible on the Nightly try build with the latest Screenshots release, received from jared.
A "Error deleting shot: 500 Internal Server Error" is displayed if you try to delete a shot from "My Shots" page.

So, probably this fix wasn't deployed to production too?

The fix should be deployed to stage (as of last night), but not to production yet

[SoftVision-CosminMuntean]

@ianb So the current version of Screenshots from production will be uplifted in Firefox?

This bug is purely on the server, and we aren't at the moment coordinating server and client releases.
