Hi Lucian,

I really appreciate your assistance since I really need that code. Unfortunately it returns an error on the header of our website with the error:

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘td_my_custom_class_names_on_body’ was given in /home/website/public_html/wp-includes/plugin.php on line 199
class=”wpb-js-composer js-comp-ver-3.6.8 vc_responsive” itemscope=”itemscope” itemtype=”http://schema.org/WebPage”>

Do I need to add the code on the very button of functions.php? Since that’s what I did. I hope you can assist me again. Thank you in advance for your patience 🙂
