Hi there,
looks like you’re using the Merch site – which has its own custom sidebar. To remove it entirely you need to:
1. Go to Appearance > Elements and delete ( or Quick Edit > Status > Draft ): the Woo Single Product Sidebar
hook
2. in Customizer > Additional CSS – remove this block of code:
/* Single Product Sidebar position */
@media (min-width: 768px) {
.single-product #right-sidebar {
float: right;
}
.single-product div.product .woocommerce-tabs,
.single-product div.product .related.products,
.single-product div.product .upsells.products {
width: 66%;
display: inline-block;
}
}
