Sorry 'GJC Web Design' and 'AH', I actually thought the error issue was above and was already reported from various people.
I'm getting emails such as this every day:
"Hello,
An error with your payment method paypal on your store xxxx. The details are logged in the file paypal.1.log.php
. The VirtueMart Team"
and this is what I see in file 'paypal.1.log.php':
"#<?php die("Forbidden."); ?>
2021-12-08 19:40:53 ERROR checkPaypalIps: Error with REMOTE IP ADDRESS = 173.0.81.140.
The remote address of the script posting to this notify script does not match a valid PayPal IP address
These are the valid IP Addresses: 64.4.248.8,173.0.81.33,173.0.81.65,173.0.81.1,The Order ID received was: UUS701103
2021-12-09 14:10:04 ERROR checkPaypalIps: Error with REMOTE IP ADDRESS = 173.0.81.140."
..... and it repeats...
I've seen various possible solutions, but no real solid solutions. I keep hearing that the fix is on the latest version of VM, but from 2019. I just wanted to point out that this issue has not really been fixed in any VM version if anyone else is still having some of these issues.
As a side note, my PayPal specifies that IPN is off, so am I forced to have this on for this to work fully? Some payment emails still go through as successful payments, but mostly they don't (as I mentioned above).
Thanks for your kind help.
