XKit 4.x Users:
Supporting 5.x is hard enough for me, so XKit 4 (and below) is not supported at all anymore. If you are on Chrome, please remove XKit by going to Wrench Icon > Preferences > Extensions and upgrade to XKit 5 using the link provided on this blog.

Chrome Users:
Before sending a bug report, please make sure that you’ve removed the “Firefox Version” of XKit, by going to Wrench Icon > Preferences > Extensions, and removing the XKit that doesn’t have the black X icon.

Follower Checker Users:
As you can see on the new Follower Checker error dialog, Tumblr returns “Internal Server Error” on some accounts when Follower Checker tries to fetch the follower pages. Even though this is beyond me, I am still trying to find workarounds to make it work on the accounts that cause the error. I am really, really sorry about this, and a fix will (hopefully) be available as soon as possible. Thank you for your patience.
