Discrepancy between visual composer preview and website

Hi,

There is a discrepancy between the visual composer preview and what is shown on my website
(www.huangkitchen.com). There are certain parts that are missing when viewed on the browser itself. For instance, there are supposed to be headers in my main page, which do not appear on the site. The “category” page is completely blank. Please help me with this issue, thanks.
