I would check TabID 99....the Links module in question (whichever one is 479), and make sure all the links...click ok.

Re: Google bot chrash my site.

Does the file exist anymore? Is that fileticket valid?

Check the url (yourdomain.com//LinkClick.aspx?fileticket=n2u0jHOVh9g%3D&tabid=99&mid=479&language=it-IT) and see if you get the same error. If you do, then it's probably that the file doesn't exist at the specified locaiton anymore (FileTickets aren't used much anymore).

You can try and block google from accessing that Url using the robots.txt, but eventually it will give up if it keeps getting 500 server errors every time it tries that location.

Do you need a DotNetNuke Developer? and Free DotNetNuke Downloads
