I you can take a look, thank you ??

For me it works fine, I can vote and the requests go through fine. I can’t find any issues with your page. Try clearing your browser cache, maybe you have old versions of rating scripts loaded.

ok not sure if that was the issue, but after upgrade to WP 5.5 it is working for me too (or bcs the update of the plugin yesterday), so hvala vam! ??
