Plugin not picking up events

Hi,

I have built a very basic plugin to respond to membership events but am unable to get the most basic functionality working. Is there something else required other than installing and enabling the plugin in order for events to be detected ?

Membership Pro version is 2.3.0, Joomla 3.5.1, PHP 5.4.31

Code is shown below.

many thanks.

<?php
/**
* @package DoofaMPro
* @version 1.0
* @author
* @copyright
*/
defined('_JEXEC') or die('Restricted access');

class plgOSMembershipDoofa extends JPlugin
{
protected $autoloadLanguage = true;

public function onMembershipActive($row)
{
$this->log('onMembershipActive for OSMembershipDoofa triggered');

return true;

}


public function onAfterStoreSubscription($row)
{

$this->log('onAfterStoreSubscription for OSMembershipDoofa triggered');

return true;

}


public function log($string)
{
jimport('joomla.log.log');
JLog::addLogger(array('text_file' => 'iantestOSMembership.log'), JLog::ALL, array('IanTestOS'));
JLog::add($string, JLog::NOTICE, 'IanTestOS');
}


}

The code looks good to me. I don't know why it didn't work. How did you test it? Did you try to subscribe for one plan from frontend of your site?

Maybe you can submit a support ticket sending us super admin account of your site so that we can check and solve the issue for you directly on your site

I have tried both subscribing at the front end and manually adding a subscription as administrator.

Thank you, I will log a support ticket.

You can also send me a copy of the plugin so that I can install and check it directly on my local computer if that's easier

That would be a good place to start, thanks.
Attached is the plugin.

Ian
