I've had a new site designed in wordpress but Google doesn't seem to be indexing.

Hi,

I've recently had a new site designed in Wordpress and uploaded to my hosting.

This was originally uploaded about 2 weeks ago.

I have a gut feeling that not all is right with my site as google doesn't seem to be indexing my new blog posts and old ones in google it has indexed from my new site get a '404' error when looking when cached.

Everything might be fine, but I would like someone to give it a quick look over (back-end of site and webmaster tools) and advise if everything ok.

Thanks
