menu problem in architecture themes

Hi. In our site www.acquerisorgive.it i upgraded the plugin wp google maps because i must insert google api code.
After this upgrade, the submenus in home page doesen't appare. Only the first item.
If i disable the plugin, all works. But i can’t keep disabled it!
I have architrecture theme v 2.0. I tryed tu sobstitute the file functions.php with the last in your site, but it’s the same.

In another my site, with theme “ALIUM”, the upgrade of the plugin don’t cause this problem.
