pop not working properly

Hi,

I’ve set up a pop-up into this page : https://valer.fr/messika/ on the “Toutes les collections” button using that code into my function.php :
/* Ajout POPUP */
function inline_popup_enabler(){ ?>
<script>
(function($){
$(window).load(function() {
$(‘.inline_popup’).magnificPopup({
type:’inline’,
midClick: true
});
});
})(jQuery);
</script>
<?php }
add_action(‘wp_footer’, ‘inline_popup_enabler’);

But it’s showing the popup content as it has a sidebar (or it hasn’t) so the content is weirdly move to the right : https://i.imgur.com/w5bYSSL.jpg

Do you know how to correct that ?

Best regards,
Clément
