Paypal payments pro fatal error in zcAjaxPayment.php

1.5.8
PHP 8.0
I have not gotten a single order in several days, and had a customer call me to let me know that they can't pay. I verified that after entering the credit card info, and hitting the continue button, nothing happens at all, and I get a php fatal error with zcAjaxPayment.php. I checked on my host's website, and it looks like they forced me into php 8.0 recently with no way of going back to a lower version, so I need to figure out how to prevent this fatal error.

I was able to find a way of forcing the site back to php 7.4, but I would really like to get the files fixed, so that if I get forced into a newer php again, I won't lose functionality.

i am guessing that this file:

includes/classes/ajax/zcAjaxPayment.php

is missing this PR.

i would ensure that you are using this version of said file.

best.

Thank you. That fixed it, but now I have a whole bunch of Undefined array key warnings now, triggered by includes/modules/payment/paypaldp.php

Thanks for tracking this down @carlwhat.

@vanhorn_s: updated file noted above is one of the many fixes in Zen Cart 1.5.8a, the first patch release to 1.5.8. It's a good practice to update to the latest at your earliest opportunity.
