I'm unsure where this problem originates, but my guess would be the instance as it's consistent no matter where I try to post (local or external communities).
Whenever I try to attach an image to a post, I'm getting the following error:
{"data":{"msg":"Error in DB","files":null},"state":"success"}
Does anyone more knowledgeable about these sort of things have any clue what that's about?
I think it was probably disabled due to abuse concerns. I remember a while back it was discovered that you could upload an image to an instance without even posting.
