Would someone PLEASE fix this?

Having typed the error message mentioned in the post below into Google, I was able to access a page that just had my previous post on it. I just don't understand: I can access all parts of my blog except the main page of my blog itself. This doesn't make any sense at all. There doesn't seem to be any way to get help specifically focusing on the issue at hand. So to any tech guys who can read this: "ARE YOU GONNA HELP ME?"
