Collection Not Showing in Backend

[Jadendreamer13]

I can no longer see a specific collection in my backend. When I try to add a product to it, I get this message:

An Error Has Occurred

It was working fine yesterday.

What collection are you referring to, please? @Jadendreamer13

I can’t send you a link, because I can no longer see it, but it was a collection called something like “Supplies for bakeries.”
