I lost my header div when I made the transition from HTML 5 to XHTML 1 Transitional

Recently, I faced a challenge while transitioning a client's website pages to XHTML 1 Transitional in order to support an API from a company called Chamber Master. This particular API handles membership information, job postings, promotions, and other data for Chambers of Commerce.

Initially, my template looked fine after the transition, but the data wouldn't load properly. And when it did load, it caused my template to malfunction by ignoring CSS and script elements.

The integration team suggested using absolute paths for CSS and JavaScript files and advised me to remove the "link" tag surrounding my CSS file declarations. Following their advice resolved most issues, however, it resulted in a new problem - my header vanished.

Previously, the HTML code should have shown:

<body>
    <div id="header">
         <nav>
    ...
         </nav>
    </div>
    <div id="main-wrapper>
    ...

But, now it appears as:

    <body>
    <div id="main-wrapper>
    ...

While the server file includes the missing portion, the rendered page fails to display it. Any insights on how to solve this?

It's important to note that the <nav> element is specific to HTML5 and is not supported by XHTML 1.0 Transitional.
