404 Not Found error when clicking post links

[orfyworfy]

Hi, we have a site at http://www.hppavilionstore.com which uses a modified church theme. It has been working great, it has 17 posts.

We are experiencing a 404 Not Found error when we click on the links from the home page. All the posts are there when we login to admin.

We encountred this problem after trying to stop a site that is blatantly ripping our images of by linking directly from his site to our images. we went into cpanel and blocked linking to .jpg files, well our images stopped showing on his site, but also on ours! We had to stop the block

If somebody could have a look over there we would much appreciate it! http://www.hppavilionstore.com we need to move forward with this project. If you need logins then please let me know, Thanks, Ian
