Attachments not working

The "Attachment" feature is not working for me on this forum. It always tells me "The file could not be uploaded." I was trying to upload a small .png picture (about 8KB).

Anyone else having the same issue?

I am working on Windows 7 and Firefox.

​Same here ( "The file could not be uploaded."  )  with OS X and Firefox 39.0.3 for a small png.

I think its a known issue. I guess we might have to wait for the brand new shiny website when its ready... 

OK, I see. That's fine I guess.
