    Have you tried it with W3 Total Cache (and other plugins) disabled? If so, does that make a difference? You may want to try a different caching plugin temporarily too, such as Quick Cache or WP Super Cache.

    The last modified header is not controlled by W3TC, it sets headers like expires, etag, cache-control etc.

    I can see in PgCache.php, there is one code block which sets the Last-Modified header. Ideally it has to be the modified date of the post, page etc.

    Code Block:
    $headers = array_merge($headers, array(
    ‘Last-Modified’ => w3_http_date($time),
    ‘Vary’ => ‘Cookie’
    ));

    What are your browser cache settings?
