Hello!
1) I have tried to change almost every option and found nothing.
There is a white space that is over top-hader element. Only pages without breadcrumbs.
2) After solving my last ticket https://www.8theme.com/topic/how-to-add-woocommerce-add-to-cart-button-to-grid-template/#post-246014, i got this problem on a single product page.
WP_DEBUG is temporary turned off so the customers won’t see error message.
Thanks!
