This version works for me as well, thank you very much!
But does this mean I have to stick with 2.2.3 from now on?
You can find the widget on http://www.irisluckhaus.de/neuigkeiten/ as 4th in the column; that empty space under the title “Meistgeklickt”.
I use PolyLang. I never altered the plugin to only show same-language results, so it usually shows a mix of both German and English posts.
Thank you for answering! I already tried to clear all cache, but nothing changed. Here’s my blog, for which I use the widget (with the title “Meistgeklickt”).
Hello! I’m having exactly the same problem after yesterday’s update. Deleting and re-installing plugin and widget unfortunately didn’t help either: My widget list is completely empty, as well as the shortcode I tried instead. On my dashboard, counts are still updating correctly.
