Somes issues getting started with Power CMS

Hi,

1. I was able to setup the mySQL database perfectly fine and I think, I could setup the database connection file correctly.

2. Thereafter I modified the WA_Globals.php file. However, I could not find the following setting in the WA_Globals.php file:
$WAGLOBAL_Root_URL = ""
Hence I did not apply the above setting. Is that required?

3. I thereafter uploaded the Power CMS in a folder called cms on my web server.

4. Though I am able to login (the URL is admin), none of the other pages display - we get an error:
Oops! This link appears to be broken.
The only page which displays fine is the page after login and the Advance Search.

I have extremely limited experience of PHP and mySQL and want to know as to which step, I have done wrong.

Could you please assist in resolving the problem.

Regards,
Anand
