My website, mediaelites.com, is run on WPMU, though at the moment there's only one blog running. When I try to add images to a post via the "add an image" window, I get a broken-image icon. Meanwhile, the usual place for those, which is mediaelites.com/files, seems to have disappeared.
This appears to have started when we hit the total of "storage space allowed." I went into the MU and added more space to the blog, but by then it seems to have been too late. Anyone ever encounter something like this?
