Thanks to anyone that can help me out.
I was trying to update some of the files on my server after making some changes. When I uploaded them via dreamweaver they seemed to be updated in the FTP folders but no changes were made when I went to the actual domain url: http://caitlinthornton.net
THEN after that failed I just tried to upload everything from scratch and now all I get when I go to the url is the "requested URL / was not found on this server" error message
However, all of the files are there and when viewed via ftp://caitlinthornton.net (the site) everything is working
I have NO idea where to go from here
EDIT: fixed the issue
