hello , i realy dumb about this , so please some help if you can.( i've read a lot of posts but i have no ideea what should i do).

i've instaled the module , it works, when i run cron ..he is sent to google, yahoo, etc . the sitemap.xml works ok on IE , but when i try to open the www.example.com/sitemap.xml in chrome it's page not found. i have on chrome an apps ..chrome seo ..and as well it says that the site has no sitemap .

the strange thing is that this problem on chrome appear only when i am login as an user ( page not found in chrome ) , but when i am as anonymus it work

does this problems affect the way that google crowls check my site?
