So I'm working on a site that has DOM included in it, and it has overwritten the uploader in the Files & Assets tab (which I like).
However my client has encountered an interesting issue when trying to upload an image to the uploader. It queues fine, but when you hit "Upload" it prompts an error
"Message from website"
The browser also shows this error in the bottom left hand corner prompt:
Message: Not implemented
Anyone experienced something similar?
