Kramer shows no incoming links

I just installed Kramer, but I can’t get it to display the incoming links from Technorati. The only output on the post page is an empty UL, but if I understand the debug message correctly, it claims Kramer is working:

<!-- KRAMER DEBUG INFO

But for the post in question (https://www.mothugg.se/2008/06/28/antiklimax-mot-fra/), Technorati lists, so far, one incoming link (https://technorati.com/posts/PvTKV2ZupBgRWYnGwglCrKHexOZgTZ%2BkVoPrWO7mvy8%3D).

Any ideas why it doesn’t work?
