the permission error is causing the issue, you need to change the permissions on the /PowerCMS/js/lighter/Fuel.php.js to allow access to it.
you may be able to accomplish this in Dreamweaver.
In the files panel, change the View Dropdown to Remote View.
Locate the /PowerCMS/js/lighter/Fuel.php.js file and right click on it. Select the Set Permissions option. set the permissions as:
Owner: Read, Write, Execute
user / Group: Read, Write
Everyone: Read, Write
If the change does not take effect using Dreamweaver, you may need to use the Hosts Control panel or an FTP program to modify the permissions.
