After you activated the plugin and provided the right absolute path to your Mage.php, add the following lines somewhere in your code where there is no header being sent:
if(class_exists('Mage')){
$status = Mage::getModel('newsletter/subscriber')->subscribe('[email protected]');
$message = ($status == 1) ? "Success" : "Fail";
}
or else you’ll get an error similar below:
