PayPal Duplicate/Double Orders and PayPal Error Log when Customer places an Order
Running Zen cart 1.5.7c on PHP 7.4 with OPC using Responsive Classic template.
Payments accepted (PayPal Website Payments Standard & Bank Transfer).
Recently We have been getting Duplicate Orders on EVERY order that came when customers chose PayPal as their payment method.
I know the great DrByte always advises NOT to use that payment method, so if anyone doesn't have to use this payment, you should follow his advise.
After doing a LOT of online research on the forum and elsewhere, I finally found a Fix that worked for us :D
It was in a post by LissaE from a response from PayPal tech support...

*Also found a link to the above post from another post which also has other suggestions by tfharman...

It suggested changing the code in includes/modules/payments/paypal.php on Line 218 from:
'redirect_cmd' => '_xclick','rm' =>[B] 2[/B],'bn' => 'zencart','mrb' => 'R-6C7952342H795591R','pal' => '9E82WJBKKGPLQ',
**TO **
'redirect_cmd' => '_xclick','rm' => [B]1[/B],'bn' => 'zencart','mrb' => 'R-6C7952342H795591R','pal' => '9E82WJBKKGPLQ',
This did the trick for us, we have STOPPED getting Duplicate Orders when customers choose PayPal.
We are still getting the following Error log PHP Notice Generate every time a PayPal order comes through :(
