It seems odd that the directory request returns a 403 and not a 404 if it's just missing - if the directory is in fact there, the 403 might indicate an issue with your sites ability to parse index.*. files (which would be odd, because index.php files in the /test directory seem to work fine), but, there still appears to a browser, that there are no WordPress files (at least not some of the ones that should be immediately accessible) at the root of fevershoes.com that I can find. They all return a 404 error.
Try it yourself
fevershoes.com/readme.html
fevershoes.com/index.php
fevershoes.com/wp-login.php
fevershoes.com/wp-admin/images/logo.gif
- then open your ftp client and visually inspect what's actually in the root directory.
The 404's indicate file not found. What do your eyes tell you when you look for them in your ftp client? And just for giggles, what is the exact file name and exact extension of the file that you're using for the landing page?
