CCAvenue Error Code: 10001 Invalid Request - Encrypted request invalid/not present, on localhost
I am getting error whenever I am trying to post data to CCAvenue on localhost for testing purpose. I am following this website http://www.phpzag.com/ccavenue-payment-gateway-integration-in-php/. I have every credential what we need.

Answer
Error Code: 10001
PHP Mcrypt module has been used to encrypt customers and merchant data to the payment gateway so either it is disabled or you have some disabled functions which is blocking mcrypt. In your PHP Configurations set only disable_functions = show_source, system, passthru, popen, proc_open. If you are on a shared hosting then contact your hosting provider to enable and allow PHP mcrypt.
at server side install mcrypt module.
sudo apt-get install php7.0-mcrypt
Then try again.
