Hi Fabian,

This question is out of the support scope but I will try to help you this time. You can add this JS code in the Theme Options > Footer > Tracking Code.

<script>
jQuery( document ).ready( function( $ ) {
    $( '#tab-title-reviews a' ).click();
} );
</script>

Have a nice day!

Hi Fabian,

Please share your website login credentials with me so I can test this. To safely include your credentials click the Insert Credentials button in the editor toolbar (see how)

Thanks!

Hi Fabian,

I have modified the given code to this one:

<!-- Change Tab Position-->
<script>
jQuery( document ).ready( function( $ ) {
    function setActiveReviews() {
        $( '.wc-tabs > li').removeClass( 'active' ).filter( '.reviews_tab' ).addClass( 'active' );
        $( '.woocommerce-Tabs-panel' ).hide().filter( '.woocommerce-Tabs-panel--reviews' ).show();
    }
    for ( var i = 0; i <= 10; i++ ) {
        setTimeout( setActiveReviews, 50 * i );
    }
} );
</script>

And the Reviews tab is made active on the page by default:
