Follower Checker 2.3 is out.

Yesterday, Tumblr made some changes that broke the Mutual Follower Check mode of XKit. I’ve made several changes, and uploaded the latest version of it.

You should automatically get the new update in a few hours.
If you don’t want to wait:

  1. Click on the X icon
  2. Click on Manage Extensions
  3. Select Follower Checker 2 and click on “Re-install / Manually Update”
  4. Refresh the tab.

Sorry about the inconvenience, and don’t hesitate to send me an ask if it still doesn’t work. Thanks for using XKit!
