Doubled main URL

[kuroi]

http://www.acquatua.it/index.php ? main_pa isn't really working. What's happening is that Zen Cart is rejecting the string after the index.php as invalid, ignoring its contents and sending you to the home page, which just happens to the same page.

You issue therefore is only that Google has picked up an invalid page link. Whether that's a dodgy link elsewhere or a Google error is impossible to tell, so I'd recommend focussing your attention on using Google Webmaster tools to request that it be removed from the index.

Also, by posting those links here you have just served them up for Google to re-index! I'll take care of that for you, but recommend against posting links that you don't want Google to index, as it's on this site constantly and most posts are indexed within minutes of being posted.
