MyBB Community Forums

I can't find my last thread that i made about this but I am trying to install Ajax chat into mybb forum located at

http://www.fearthefayz.com


Now the directions say
1. Upload to the server
--------------------

Upload the chat folder to your server into your MyBB forum directory:
e.g. http://example.org/mybb/chat/

Okay so I logged into my Cpanel and uploaded the ZIp file for ajax into my forum root directory public_html

And then I extracted the files into the same directory, public_html


so then Step 2 says

2. Creation of database tables
---------------------------

Execute the provided installation script by visiting the following URL with your browser:
http://example.org/mybb/chat/install.php

Replace "http://example.org/mybb/chat/" with the real URL to your chat directory.

I replaced example.org with http://fearthefayz.com/mybb/chat

and i get this error message
The requested URL /mybb/chat/install.php was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 Server at fearthefayz.com Port 80

What exactly am I doing wrong? I really could use some help.
Thanks

Check that the file ./chat/install.php actually exists on the server.
