You’ll also need to check if $_POST["product"] is empty in the same function.

Solution can literally be

function save_detail( $post_id ){
    if ( defined('DOING_AUTOSAVE') && DOING_AUTOSAVE || empty( $_POST["product"] ) ) {
        return $post_id;
    }
    update_post_meta($post_id, "product", sanitize_text_field($_POST["product"]));
}

This breaks the WooCommerce settings pages, not just by using a separate plugin.

In “class_googlepay.php” the function payment_method_type() have to change the empty check, since $method_type can be empty.

On line 117 I added && !empty( $method_type )

if ( empty( $google_method ) && !empty( $method_type ) ) {
         set_transient( PREFIX . '_google_method', $method_type, \HOUR_IN_SECONDS );
         $google_method = 'googlepay';
      }

That actually worked.

I would have thought adding the filter to the theme would be enough, especially since only WooCommerce is a MU plugin and not this plugin. Anyways, thanks for helping out ??

I’ve tried that filter without success. I could not get it to actually trigger.

Not sure if this is some incompatibility with Roots Sage, but I could not get this message to appear, but if I use a normal WordPress hook like init I could see the test message:

add_filter('wpo_wcpdf_is_woocommerce_activated', function () {
   die(var_dump('test'));
});
