There seems to be a problem with Activity and Dashboard pages, with some pages not loading, notes disappearing and XKit double or even triple posting some posts. There are some reports of a “Bad Gateway” page appearing instead of pages requested. It doesn’t happen on all accounts, but it looks like Tumblr is having some technical difficulties.

Some features of XKit such as One-Click Postage and TagViewer will not function properly until these server-side problems is fixed.

Unfortunately, there isn’t much I can do about this, I apologize for that.
