We are getting an error "Internal Server Error (500)",
Problem:-
Case 1:- When User is NOT LOGGED IN
in this case when user on checkout page, We are asking them to create an account with us, But in this case they are unable to pay via our payment gateway (Razor Pay), They are getting Internal Server Error, I have cross checked everything, the setting of Razor pay and setting of Woo commerce, I don't know why
Case 2 :- When User is LOGGED IN
In this case if user buy any course this works fine.
Wplms do not have any payment gateway and hence we rely on third party plugins for this, wplms do not make any changes related to it and it cannot conflict with the payment gateways.
So the issue is originally between your payment gateway and the woocommerce, please try contacting your payment gateway for this issue.
