Didn't work

Installed, set up, no popup. Switched off W3 Total Cache, no popup. There’s no test button, no cookie clearing option or anything, so hard to tell whether it thought I’d visited or not.

Switched to WP Super Popup and it worked perfectly. The loss of links to social sites is bearable – can add those in a widget.
