I don't know if anyone else has been encountering this problem, but for the last few days I have been having an issue when trying to create new sections in the vocab list maker. It seems as though maybe it's something the great firewall is blocking, because when I work through a VPN on either server it doesn't run into this problem.
When I create a new section, the section will appear, empty, with no problem. I can click on "add words", and enter words with no problem. The problem comes when I hit "save changes" - the page shows the "saving" screen and sits there indefinitely.
When I use a (ghastly slow) VPN and the .com site I do not encounter this problem. I also do not encounter it on the .cn site through the VPN. With no VPN, I pretty much cannot access the .com site.
