Popup rules are ignored completely


I have installed Popover plugin version 4.4.5 and set up a popup with these rules:

– Popover shown less than 2 times.

– Visit not via an Internal link.

– Not on specific URL.

But the popup comes up every time, every where.

It seems like it ignores all the rules.

This is not a multi-site and I am not using domain mapping plugin (read it in an older thread).

I am using a caching plugin.

What could be the problem?

Thank you
