I'm having the same problem. It started when I was trying to upload an image. Now I can not even get on to the Auctiva.com site. I tried using a link to file a support case with no luck. Also, on eBay... images will not supersize.
I use Firefox and the error message I get when trying to do all of the above is...
"Page Load Error
Connection Interrupted
The connection to the server was reset while the page was loading.
The network link was interrupted while negotiating a connection.
Please try again."
