The post grid works fine. But the post navigation does not work yet.
For example going to page 2 gives nnot found and the url :

https://hetsocratischgesprek.nl/socrablag-test/2/page/2/

https://hetsocratischgesprek.nl/socrablag-test/page/2/ does work fine. But could not find the code in the widget to fix that problem. 

I am not knowing why but I did discover that deactivate "Event Espresso"  did 'solve' the problem.
So I have to dig further to find the cause.
