Paypal IPN no longer works after upgrade

[nfried]

After upgrading to WHMCS 5.0 recently, my Paypal IPN for subscriptions created before upgrading have stopped working.

 

IPN for new orders/subscriptions created after I upgraded seems to work properly, but payments on subscriptions created before I upgraded are no longer being automatically marked as paid. They were certainly being automatically marked as paid before I upgraded WHMCS.

 

Has anyone experienced this after upgrading? Is there a fix?

 

Any help would be appreciated.

I had the same issue

Checked everything, no issue found when upgrading from v5.0.2 to v5.0.3 (it was fine the week before when upgrading from v4.5.2 to v5.0.2)

 

I decided to go back to basics

Removed the PayPal email address from WHMCS

Logged out of WHMCS

Logged back in then added the PayPal email address

 

Went to PayPal and swapped to a secondary email address

Logged out of PayPal

Logged back into PayPal, then swapped back to the PayPal email address installed in WHMCS

 

Not had any problems since, weird

 

Try that and compare

Check your Billing > Gateway Logs page in the admin area. Do you see "Invalid Receiver Email" in the Result column? If so, here's how to fix that

Didn't make any difference, there was no change of email address, either in WHMCS or PayPal; this only occured after upgrading from v5.0.2 to v5.0.3

I suspect the email field in the MySQL database was changed, so was not picked up correctly, and performing the above reset the PayPal email address into the correct place in WHMCS
