after last update not work my plugin!
I also bought the Pro version but it still doesn't work.
Before update
when I opened each individual country all the articles written by category appeared (with your plug in).
Example
Clicking on Ukraine, I saw all 11 articles with POST GRID written about Ukraine but now it is no longer so.
this is the map of Europe
