Upgrade to Emerald/PayPal - problems if change web directory??

Will changing to the root directory cause problems with the PayPal IPN for existing recurrent subscription payments?

Absolutely! Even if you do not move it to the root. Because name of the extension is changed to com_emerald. So URL is different. We would leave com_jcs with is inherited yet from JContentSubscription for Joomla 1.0 but new JED rules does not allow that. So we had to rename it.

I think the only what is to create small redirection plugin with would transfer all IPN requests to correct URL. In yoursubfolder, leave index.php and add there code with will check if it is a request with post data and to component com_jcs and task create, redirect to new URL including all post data.

Or, if redirect does not work wit IPN (i do not know how it would behave with redirects) just tri to include index.php of your new folder. But do not forget to change

$_GET['option'] = 'com_emerald;

$_GET['task'] = 'plans.create';

$_GET['processor'] = 'paypaypal';
