WP Popular posts work random

Hi,
I have the same problem that I had only on https://www.automotivspace.org also in https://www.automotivespace.it.

How you can see in the widget clmn the plugin works well in home page, but if I open a post the widgets are empty (www.automotivespace.it and https://www.automotivespace.org)

Please, give me the right support

Thanks

Pietro
