Is this a Classic layout problem?

Hoping im posting in the right place.

first of all sorry for my english.

I have been working in my page and i have discovered this problem when i made a sale with a dummy account. the main page is behind the left sidebox column.
is only on two or three pages not at the main only at the shoping cart.

Wich could be the problem? the scroll new products side box?
I include a image of my problem.
My site is https://www.metalnorte.com.mx/tienda

thanks for the help

The answer is yes you are using the combination template with 2 stylesheets.

One can correct these issues but you will be fighting this for quite a while and some are difficult to trace.

Create your own template from the template default file set or dowmload one of the free templates in the download area that are version 1.3.x based.

These issues will vanish and musch easier ones will replace them.
