Ah, then it might be related to Editor vs Reality (Self-Hosted) which leads to a documented issue in GitHub: Cannot generate assets (cards, admin-auth, etc) on local windows install · Issue #14278 · TryGhost/Ghost · GitHub.
I’m guessing the logs for this are the ones found in C:\Ghost\content\logs and primarily it’s the ...error.log that contains the information needed in this case? Since it’s a local installation I figure that the logs don’t contain any sensitive information, except for maybe an email address or something like that somewhere, so I should be able to upload the logs somewhere without having to fine-comb them first?
Should I report this as a bug in GitHub, just like the one I linked to above?
