Hi Michael,
Thanks for reaching out.
The sample code tested in the local environment and seems that it working fine. There might be some other issues that are blocking the code to work. The code that worked is given below:
function reverse_review_order( $x )
{
$x['reverse_top_level'] = true; return $x;
}
add_filter( 'woocommerce_product_review_list_args', 'reverse_review_order', 999 );
Remember that the above code will work if copied as it is and don’t conflict with any existing style.
Please note that the code provided serves only as a guide to help you get started custom coding on your own if there’s no option offered in our theme or the products we bundle.
We do not provide support for custom codes that means we can’t fix it in case it conflicts with something on your site nor will we enhance it.
If that does not work, I would suggest you troubleshoot the common issues related to it.
1.Plugin Conflict
2.Child Theme Related issue
3.CSS/JS Customization
4.Disabling Cache
If you discover that an issue is coming from a custom code or 3rd party plugin, kindly consult with a developer or contact the plugin author. Please note that we do not provide support for custom codes and 3rd party plugins.
