Logout-Redirect does not work

Hi,

I installed the above plugin by putting it in wp-contents/plugin folder

Changed the configuration section to below:

//


//

//—Config


//

//


//

$logout_redirect_url = ‘http://goablogs.com/’; // the url you want users to be redirected too after logging out

//


//

But somehow it still does not work ?

PLease can someone help me
