How do I disable the sub header in BuddyX Pro?

There is no built-in setting in BuddyX Pro to disable the sub header. The reason is that the sub header is a core part of the theme layout, designed to display important page titles, breadcrumbs, or navigation elements. Since many users rely on it for consistency across their site, the theme does not provide a direct toggle to remove it.

However, if you don’t need it, you can simply hide it with a bit of CSS. Go to Appearance → Customize → Additional CSS and add the following:

.site-sub-header {
    display: none;
}

This will hide the sub header throughout your site.
