安装后在Moodle 2.7中出现错误

I Installed Moodle 2.7 by using XAMPP and it displayed the admin profile page. I am getting error if I proceed to any other page or open the application again

Notice: Undefined variable: CFG in C:\xampp\htdocs\moodle\index.php on line 31
Notice: Trying to get property of non-object in C:\xampp\htdocs\moodle\index.php on line 31

Sounds like the config.php file isn't correct.

Have you got something like this at the top of your /config.php file

unset($CFG);
global $CFG;
$CFG = new stdClass();

Have a look at /config-dist.php for an example.
