Hi,
Please take a look at the real source of the page and not at the DOM.
In Firefox you can "see the source" and the errors will be in RED.
You can also use online "checker" to see the errors.

But for what I can see, your issue is not HikaShop.

By the way, do not send me private message, use the "contact us" form instead.
