PayPal IPN Listener returns 404 error.

I recently upgraded to the latest WordPress, WPMU DEV Dashboard and Membership 1 to 2, since then, the PayPal IPN listener isn't working for me. It returns a 404 error. PayPal even emailed me mentioning by listener is failing.

    Hello Brett Kokinadis ,

    Hope you are well today. I have had a look at the transaction logs on {SITEURL}/wp-admin/admin.php?page=membership2-billing&show=logs and I was able to confirm the PayPal IPN is working well and I do see some IPN calls for today with the corresponding invoices marked as paid for example {SITE_URL}/wp-admin/admin.php?page=membership2-billing&action=edit&invoice_id=22085 . Could you please help identify which transactions are failing?

    Warm Regards
    Paul Kevin

    Maybe something changed since last night, but payapl for the past few days has replied:

    Please check your server that handles PayPal Instant Payment Notifications (IPN). IPNs sent to the following URL(s) are failing:

    https://{SITE_URL}/ms-payment-return/paypalstandard

    If you do not recognize this URL, you may be using a service provider that is using IPN on your behalf. Please contact your service provider with the above information. If this problem continues, IPNs may be disabled for your account.
