do_shortcode / item portfolio

Hi,

I have a problem with layerslider :-(

In header.php i have this :
<?php
$url = $_SERVER[‘REQUEST_URI’];

if( strstr($url, “catalogue-hebdomadaire”))
{ echo do_shortcode(‘[av_layerslider id =”15″]’); }
elseif( strstr($url, “catalogue-mensuel”))
{ echo do_shortcode(‘[layerslider id =”16″]’); }
else { echo do_shortcode(‘[layerslider id =”11″]’); }
?>

It’s work fine for each page, post.. but no for item portfolio
contact page (slider 11 OK)
http://boreale.pro/contactez-nous/

item portofolio exemple (i have this [layerslider id =”11″] ):

Do you have any suggestion ?

Thanks
