Old domain reference after moving in link?

I moved a site I worked on. The theme we modified was based on portfolium and had the following code for a back to blog link.

function get_blogurl() {
    if (get_option('show_on_front') == 'page' && get_option('page_for_posts') != 0) {
        $blogpage = get_page(get_option('page_for_posts'));
        echo $blogpage -> guid;
    } else {
        echo get_option('home');
    }
}

When I click the link to return to the blog from a single blog page, it goes to the right url, but still on the old server. So it goes to: https://caseydillon.com/?page_id=4 when it should be going to: https://bronzesf.com/?page_id=4

I have changed the WordPress address and site address and the site otherwise knows where it is hosted.

What am I missing here?

Thanks a lot for any help!!!
