Make the woocommerce shop page full width

Can you provide a link to your site please and I’ll inspect further for you?

Thanks.

Thanks, do you mean the entire site or a specific page in particular?

Which specific page though, your store product pages?

You can add this to your Child Theme style.css file, or by using a Custom CSS plugin.

.single-product #primary {
    width: 100%;
}
.single-product #secondary {
    display: none;
}

Hope this helps.
