Popup & slide in dont display - missing the call to ???

So i have installed both the popup & slide in plugin, i only really need one of them to make a call to like my facebook page (with thumbnail of those who already like it)

But none of them are working, i see with the popup addon that my active theme:

"Is missing the call to <?php wp_head(); ?> which should appear directly before </head>
Is missing the call to <?php wp_footer(); ?> which should appear directly before </body>"

yet when i look at the code from the theme it is there (but i am no expert so i may misread it)

Any idea of what i need to change ?
