Footer out of the page in product details pages

[fgonzo92]

Hi everyone,
first of all I apologize for my english and please help me, i'm new in the Forum. 
I have a problem.
In my products details pages only, the footer is out of the main div and it appears "out" of the page, with a white background instead of its classic background.
In the others Virtuemart pages there isn't this problem.
Can you help me to fix it?
Thank You. 

I attached two images to let you understand better what is happening.

you give no versions or what template your using or a url - how could anyone help you except to say there must be a closing </div> missing ?
