there is a website www.cubestat.com, which tells about your website. i have a website www.livetvleak.com. yesterday when i tried to check the status of my site, it shows at the Title: 406 Not Acceptable. What this means?? please help me. what are the disadvantages of this and how can i resolve this problem?

I would recommend trying again to rule out a temporary problem. Still problems? Send cubestat a message through their online "Contact Us" form.
