problem in the footer position...

Dear friends,
I have a problem with the text line position (footer) where are the copyright information.

It remains a blank space at the end and almost always the line of text is cut off. only on internet explorer do not experience this problem ... this is a news!
Can you help me solve this problem? I would like the page to finish with dark gray background, without that useless white stripe.
The website (online) where the problem occurs is as follows: www.duomopolistena.it

thanks for the support

I'm sorry but I just found and fixed the problem by changing the file layout.css line 196.

Now you can see well on all browsers I tested.
