many years ago i moved my whmcs install from a sub directory to root and reset the IPN Url to point to the new location. all works fine with new subscriptions but have an issue with old subscriptions.
I am receiving warning emails from paypal that IPN notifications are failing from old clients who have active subscription payments, the failed URL is from when the whmcs install was in the sub directory.
How can i correct or put some sort of redirect in place to point the old IPN URL to the correct one, or if anyone has found another way to sort this issue.
I am using version 8.1.3
Thank you
