Adjust header of the product page

Guys, I can't figure this one out. On just the product pages in Hikashop, my header on the website gets buried by the menu. But on all other pages on the website, it's fine. Please see the Attached JPG screenshot for clarification. Where can I fix this?

Thanks

Hi bigchumpy,

Isn't it due to the slideshow under the banner in your website ?
This slideshow is present in the "not working" page and not on the "working page".

Xavier,

Thanks for the reply. Indeed it is the slideshow, but I can't figure out why the product pages are different or where to adjust?

bigchumpy, the problem seems to be a template problem.

It didn't come from HikaShop, you need to contact your template provider.

When you are on the product page, you need to add a padding-top:20px; on the div with the id "headerbar".
