As today’s “invisible” Tumblr change broke a huge part of XKit, I’ve updated several extensions to work with the changes. 

The following extensions are now updated to work with the changes: XInbox, Timestamps, Reblog Yourself, Read More Now, Post Block, Outbox and Old Notifications.

Fortunately, a part of Interface was ready that speeded (or is it “sped”?) up the process. But it was not complete (and needed changes in order to work with Tumblr changes), so you also need to update XKit Patches.

You can wait for an hour or so for it to update itself, or follow the instructions here. Don’t forget to update the extensions manually if you want to get the updates right away.
