I followed the steps of installation, and when i try and go to " http://babyitsourworld.com/freichat/installation/index.php " it says:

The requested URL /freichat/installation/index.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.

I followed the instructions. the frei chat folder is installed in my : /public_html/plugins/authentication/joomla/freichat path. and i extracted it.

I'm still having trouble. Not sure what i'm doing wrong.

Is your Joomla installed in this directory /public_html/plugins/authentication/joomla/ ?

That is does http://babyitsourworld.com point to /public_html/plugins/authentication/joomla/ ?
