A couple of days ago, a few XKit users told me that Quick Tags and TagViewer icons would not show up on their tumblr.com/blog/[blog name] pages.

I could not reproduce the error myself until someone pointed out that they had an extension called Unfollower Hater, and the problem went away when they disabled it. (thank you, by the way! =3)

So I’ve downloaded it to try it myself and, yes, that extension not only blocks XKit from putting the Quick Tags and TagViewer buttons when on a /blog/[blog name] page, but it also causes problems with Blacklist and more. (The Javascript console is full of error messages when it’s active) The problem goes away when you disable it.

I’m still investigating what is going on, but it looks like it has some code that breaks XKit, and I doubt there is much I can do about it, so for now, you have 3 choices: (1) remove Unfollower Hater (2) write to the author of it (3) or, disable it and only enable it when you want to check who unfollowed you.

I’m sorry about this, but (at least) for now, it sounds like it is something that is beyond my control: not only it’s an extension not written by me, the code is in Spanish, so it’s kinda hard to understand what is going on, so I can not provide any help to you as long as you have it installed. Even if I could speak Spanish, and figure out what is going on, I probably would have to re-write a huge part of XKit, and with 90% of my time going to fixing stuff Tumblr breaks with updates, I can not handle more.

Thank you for your understanding.
