Negocios del Web Posted March 6, 2018 Share Posted March 6, 2018 Hello, I've been configuring the PayPal module for more than 6 hours. The configuration is in SandBox mode. The paypal account has the IPN configured https://whmcs.domain.com/. The charset is in UTF8. When accessing: http://whmcs.domain.com/modules/gateways/callback/paypal.php There is an error 406. Any solution? Thank you Link to comment Share on other sites More sharing options...
