URGENT: Image Links Not Working Properly on Mobile

Hi,

On i-phone, when clicking the image links I have to click more than once to open the link. I was given below code from another thread but it didn’t work even I cleared cache and refresh the page. I’m hoping to launch a website by end of today and I need this issues resolved asap.

// custom script
add_action( ‘wp_footer’, ‘ava_custom_script’ );
function ava_custom_script() {
?>
<script type=”text/javascript”>
(function($) {
function a() {
$(‘.avia_image’).on(‘click touchstart’, function(e) {
var link = $(this).attr(‘href’);
window.location.href = link;
});
}

a();
})(jQuery);
</script>
<?php
}
