Which errors ?

Have you tried without your robots.txt ?

You have it in your web-root. Try removing it, if there is no difference, just put it back again (so make a copy first). For more info google "robots.txt".

You may want to establish a webmaster's account with Google, and submit your site. You can then get more detailed information about Google's crawlers and other stats.
