I am having an issue with EasyStore during checkout with PayPal.
JoomShaper\Plugin\EasyStore\Paypal\Utils\PaypalApi::getAccessToken(): Return value must be of type string, null returned
It appears when you fill out the information and click the "pay Now" button
I have checked the keys from PayPal and the Mod Security at the server level
