pop up does not show

Hi,

The popup works nicely on the blog of this site (another wp) but would not work on the main site, e.g.
http://picrest.co.il/%D7%92%D7%91%D7%99%D7%A0%D7%95%D7%AA/%D7%A2%D7%95%D7%92%D7%95%D7%AA-%D7%94%D7%92%D7%91%D7%99%D7%A0%D7%94-%D7%94%D7%98%D7%95%D7%91%D7%95%D7%AA-%D7%91%D7%99%D7%95%D7%AA%D7%A8-%D7%91%D7%A4%D7%A8%D7%99%D7%A1/

I tried to disable the security plugin and remove the footer fb box, but still does not show

thanks
guy
