This is a known issue with the /ipn_main_handler.php: https://github.com/zencart/zencart/issues/7767

It'll be partially corrected in zc223 and later (including zc300). For earlier installations, you can start by making the change to add observer initialization to the paypal_ipn startup: https://github.com/zencart/zencart/pull/7843/changes

I have upgraded to Restful 2.10 using ZC 2.2.1 and PHP 8.2
I cannot access the Payments page in admin and an Error 500 is produced (doesn't seem to like 'sniffer'). Here are the logs :-

go here:

/zc_plugins/PayPalRestful/v2.1.0/catalog/includes/modules/payment/paypalr.php on line 497.

and try changing:

//from:
if (!$sniffer->index_exists(TABLE_PAYPAL_WEBHOOKS, 'idx_pprwebhook_unique')) {
//to:
if (!$sniffer->indexExists(TABLE_PAYPAL_WEBHOOKS, 'idx_pprwebhook_unique')) { 

best.

Thank you @carlwhat. Sniffer fix worked

[lat9]

v2.1.1 of PayPal RESTful (Encapsulated) is now available for download. That version corrects the "$sniffer" bug reported above.

Please use that version instead of v2.1.0. Thanks to @cheddars for the report and @carlwhat for the correction.
