YNFA.NET

Hi,

I want Pop up to action on the homepage only and only when the viewer is not logged in. As far as i can see i have set the settings correctly but the pop up is not working. could you take a look at it for me?

My goal is to have just an image as close to full screen as possible pop up and then not show again till the next time the viewer navigates to http://ynfa.net.

I am thinking there is a clash with W3 Total Cache yet again. I have no choice but to use the W3 plugin so removing it is not an option.

I have allowed access to the back of the site.

Many thanks
