I installed the PrestaShop Checkout module and the Official PayPal module in my PrestaShop 8.1.7 and linked my PayPal (business) account. However, why every time I try to test a payment with my another Paypal (personal) account, both modules always gave me the same error "Sorry, something went wrong. Please try again." ? Which always redirect to this link : https://www.paypal.com/checkoutweb/genericError?code=REVGQVVMVA%3D%3D&cancelLink=&merchantName=
Someone suggested clearing the cache and cookies, which I did, but it still didn't work, even when I tried it in a different browser and even I tried to make another personal Paypal account, but still same. Then I tried twice with my credit cards, first with my Visa card and then with my Mastercard, but both attempts gave me the message: "Something went wrong. We'll take you back to checkout so you can try again". And I received notifications on my phone from my credit card issuers stating that the transactions failed.
I have tried disconnecting my PayPal business account from my PrestaShop and connecting my PayPal personal account instead, but I still got the same error messages. So, what’s causing the error messages that prevent me from trying make payments? Is there something that needs to be configured on my PayPal account? I truly appreciate for your help, thank you.
additional notes:
I use Prestashop 8.1.7 that running on PHP 8.2 with Prestashop Checkout module 8.4.0.1 and Official Paypal module 6.4.2
I saw in error_logs there repeated error like these
