install using phpstudy integrated (apache php7.2.10 mysql5.5) environment under opencart3 win7 environment;
show that CGI / FastCGI has stopped working when submitting an order;

payment/code.php confirm

:
code.php confim

;

model/checkout/order.php addOrderHistory :

strangely, $this- > model_checkout_order- > addOrderHistory (6,1) reported an error.

and $this- > model_checkout_order- > addOrderHistory (7,1) prints normally, that is, as long as the first parameter < = 6, there will be a prompt that CGI / FastCGI has stopped working!

at first, I suspected that it was the mail () class, even if the background setting turned off mail!

are there any students who encounter this kind of problem?
