Portfolio filter causes loading errors in testimonials

Hello
When I insert the code to display a specific category in the portfolio element, or even when I select one of the categories in the portfolio element, the images in the testimonial do not load correctly.
I enter the following code in my funticons.php. This is in accordance with the instructions on the themes website.

//——————————
// php – Open portfolio category
//——————————

function select_portfolio_filter(){
?>
<script>
jQuery( window ).load(function() {
jQuery(‘.inner_sort_button:eq(2)’).click();
});
</script>
<?php
}
add_action(‘wp_head’, ‘select_portfolio_filter’);

Example

Do you have a solution for this problem?
