There was a problem that caused a “real_html is not defined” popup to appear while using Notifications+, which I think is due to a Tumblr change. I’ve fixed it, and you can get the update from the XKit Control Panel.

Also I’ve noticed that on some posts and replies, the notes count does not load, gets stuck at “Loading”, which I also suspect to be due to a recent change. I’m going to take a look at what might be causing it and provide a fix as soon as possible. Thank you.
