403 Error

[Max Kling]

I set my site suscessfully up about a week or so ago.

Just recently it started going to index.php instead of index.html when you type in my domain name. Well the index.php was from the forum software because I didnt download it into a directory just the regual / directory. So today I got tired of it and erased the forum software and reinstalled it in /forum. After I did the I get a 403 error when going to my domain name. But if you type out the whole url for the index file it works. I can not figure this out. Can someone help me or point me somwhere to look.

Domain is http://www.yourundergroundworld.com and URL is http://yourundergroundworld.com/index.html

Edit, nevermind I just had to edit the .htaccess file. I guess the forum software changed it when I installed it.
