Blog shows file directory

Earlier this year I abandoned my blog to build my portfolio site which is on the same server and is currently accessed through http://www.gilesnorway.com. Originally, before building my portfolio site, my blog was accessible through that same address.

I’m not sure what I did to keep visitors from seeing my blog, but now I’d like to add a link to my blog ON my website. There IS still a “wordpress” folder in my directory. AND I can still manage to access the admin page and view the posts in the edit format/interface. BUT if i try to actually view the post in the blog I am sent to my portfolio site. AND if I enter http://www.gilesnorway.com/wordpress I see a file directory.

So I guess my database still has all of my entries, comments, etc. But I’d like to make it all live again.

Has anyone seen this before? And how did you solve the issue?
