How to prevent clicking on posts

This may help, add the following code to WordPress Dashboard > Appearance > Customize > Additional CSS :

.portfolio_slide_loop.wow.fadeInUp {
    pointer-events: none;
}

If you need something more convenient, then use jQuery, add the following to in your footer.php just before the tag. :

<script>
jQuery(document).ready(function($){
$('.portfolio_slide_loop.wow.fadeInUp').contents().unwrap();
});
</script>

If you still have problem in implementing one of these, you can directly contact me.
