If you are on Firefox and if you have upgraded to XKit 7.1.2 or above, under normal circumstances, the Reblog/Follow/etc buttons that appear on top-right of the blogs should be working.

I’ve just checked, and they are not. On some blogs, it even shows a “Not Found” error where the buttons should be.

This continues even after disabling XKit, so there is nothing I can do about this. It is not related to XKit, but a problem on Tumblr’s end, and I think they are working on fixing this. Again, I’m really sorry but there is nothing I can do about this.

Update: Looks like this is happening on people using Chrome and Safari too, getting the “Not Found” page also. Again, this is a Tumblr bug that I can not fix.
