Reply To: smartphone products page / espace under Menu

This empty space is created by your custom code (https://prnt.sc/e_bRmbXtfV3Y) that affects all pages with page titles, including store page title. If you want to make this code not work on the store page, you need to modify your custom code by excluding store page from its selector:

1. Find your custom code (https://prnt.sc/e_bRmbXtfV3Y):

.page-title {
	padding: 170px 0;
}

2. And replace it with the following one:

body:not(.post-type-archive-product) .page-title {
	padding: 170px 0;
}

Kind Regards
