PHP Deprecated Warning

[NWCE]

I am running Zen Cart v.2.1.0 and haven't made any changes to it, my Paypal or my PHP version, but just today I started receiving the PHP deprecated warning of:

[10-Oct-2025 13:55:49 America/Dallas] Request URI: /shop/index.php?main_page=checkout_process, IP address: 74.110.202.141, Language id 1

--> PHP Warning: Undefined array key "PAYMENTINFO_0_TAXAMT" in /home/mystore/public_html/shop/includes/modules/payment/paypalwpp.php on line 514.

I have read in other posts about it being hard to update the payment modules due to the large variables of testing it.....so just thought I'd post it to possibly help with a future upgrade.

Hope this helps,

Jeff

Hmm, is that repeatable? If so, please enable the module's debug-to-file. Once you've captured the debug-output, send me a PM and I'll send you my direct email address so you can send that debug-output for review.

Sure thing.....I will turn on the Debug now and send you a PM later today with its output.

Thanks,

Jeff

While the line numbers are a little different, I think this fix is what should address that.

Thanks Dr.Byte....yes, this has fixed this PHP...as I have applied it and have had many orders come through without error.

Thanks for posting this!

Yep, this is the fix. I have applied it to several carts already.
