mcrypt_module_open

[andmax]

I have just changed my Hosting server and now are getting this error in my billing software where the credit card details should be shown.
Fatal error: Call to undefined function: mcrypt_module_open() in /home/andmax/public_html/billing/encrypted/commonfunctions.php on line 603

Clientexec has sent this response:
It is likely that you do not have mcrypt with curl ssl support compiled into your PHP. You must have your host re-compile PHP with mcrypt and curl ssl support in order to store credit cards in Clientexec. It is a requirement if you plan to use a merchant gateway such as Authorize.net, etc.

Can anyone help me with this issue.

That's exactly what you need to do. Go into WHM > Apache Update > (Load Previous Config - if the option is there) and then additionally select the PHP modules mentioned, i.e. curl, curl ssl, and mcrypt. Then start the build and wait until finished - can take quite some time.
