Hi All,

I am using 1.5.8a version with PHP 8.1 and have been getting these error logs lately as shown below.

Do I need to update the module as I have shut it down to see if I get any other errors.

As always if someone can point me in the right direction it would be appreciated.

That modification just removed my PayPal Express Checkout (rev1.5.8) and only left PayPal website payments module.

I had to delete the modifications to get my PayPal Express modules back again

Did I do something wrong?

Sorry my error did not add the green lines.

Looks ok now.

Hi

This is the new error log

[14-Sep-2025 22:17:19 Australia/Sydney] Request URI: /ipn_main_handler.php?type=ec, IP address: 149.167.180.176, Language id 1

--> PHP Warning: Undefined array key "L_ERRORCODE2" in /includes/modules/payment/paypalwpp.php on line 3110.

Any assistance would be appreciated.

You're making a lot of work for yourself (and others) by trying to correct issues in various zc158a-era scripts that have already been corrected over the past 2 1/2 years.

Rather than focusing on correcting those issues, might I suggest that you look instead to upgrading your site to zc210?

Thans for the suggestion but would it not be better to fix what little issues that I have prior to starting a new lot of problems.

The PayPal and AUPost are about the last issue I have with the site at presnt and after changing the code (PayPal) I am now getting more errors than before.

I am trying to start up a local copy of 2.1 so I can test modules that I need in the new version of zencart.

This is like starting now developing software for Windows 10
You're investing in software that is PHP 8.1 compatible which is going to reach it's End of Life within several weeks. 100% sure
