error 404 when posting in the gallery?

Meraki

I've been trying to post on my gallery but everytime i get an error 404, why? Are the servers down?

Have you successfully posted to the gallery before? How big is the file, and what format? The Daz gallery has a stated upload limit of 10MB, although in my experience it fails if the file is over 8, and it will only accept files in certain formats.
