problem with the urls with 2.7

Hi to everybody, can anyone help me to understand why my new site after upgraded it to 2.7 version the urls are like the example written below:?

http://www.lombardiniricambi.it/it/lombardini-3ld
instead to be
http://www.lombardiniricambi.it/lombardini-3ld

Now with the 2.7 version the site writes in the urls also the kind of language /it/

Thanks in advance
lorenzo

Go to admin area > global and misc settings > localization settings and ensure that "SEO friendly URLs with multiple languages enabled" is disabled

Thank's Andrei .... you were right...like always :-)
