[Solved] Fixing scroll issue after comment posting (Sticky Header Menu)

In case if your current active theme has Sticky Header Menu, you may have some issues with the scrolling position after posting a comment. To get it resolved use the hook-code provided below:

add_filter("wpdiscuz_js_options", function($options){
    if (!empty($options["scrollSize"])) {
        $options["scrollSize"] = 130;
    }
    return $options;
});

You'll just need to change the red marked value as it's necessary in the case of your website. 

Put the code in the WordPress active theme functions.php file (more information on how to add insert custom code).
