Hi there, 

I recently had problems getting the woocommerce demo page header/wrap off of my shop page... I was able to get it off with the code below, however, it's still appearing when the page loads - see screenshot. 

body.archive.post-type-archive.post-type-archive-product.theme-salient.woocommerce.woocommerce-page.woocommerce-js #page-header-wrap {    display: none !important;
}
body[data-bg-header="true"].archive .container-wrap, body[data-bg-header="true"].category .container-wrap, body[data-bg-header="true"].blog .container-wrap {
    padding-top: 0px !important;
}
p {    padding-bottom: 0px !important;
}
.nectar-shop-header {    display: none !important;
}
.container-wrap {    padding-top: 0px !important;
}

Thanks Tahir, it seems that fixed it.
