I want to add the Authorize.Net payment gateway for bookings. But the Authorize.net addon is not working correctly. At the time of installation it’s show the error under this file on line 77 /plugins/wp-hotel-booking-authorize-payment/inc/class-hb-payment-gateway-authorize-sim.php Here is the code: if ( $this->_settings['sandbox'] === 'on' ) { $this->_authorize_url = $this->_sandbox_authorize_url; } else { $this->_authorize_url = $this->_production_authorize_url; } And we can’t enable the Sandbox mode and the fields for the ” API Login ID ” & ” Transaction Key ” is not working and not saving the keys.
