Opencart mcrypt_create_iv error after account transfer with cPanel

Question

I transferred my hosting account on a new server with cPanel. After that, Opencart started to give this error:

Fatal error: Call to undefined function mcrypt_create_iv() in /home/arkadas/public_html/system/library/encryption.php on line 8

I installed mcrypt on my new server but it is still same. I checked all opencart forums but couldn't find any solutions for this.

Answer 1

The only possible cause of such an error Fatal error: Call to undefined function mcrypt_create_iv() is that mcrypt PHP extension is either 1. not loaded or 2. not installed at all.

Things to do:

1. make sure the mcrypt is installed on the server - if not, install it if possible (if not, ask Your provider to install it for You).
2. if yes or after installing make sure it is loaded by PHP in php.ini - remove the leading semicolon ; from the line ;extension=mcrypt...

On Debian system (Debian, (K|U|X)buntu) You can install it using this commands:

sudo apt-get install php5-mcrypt
sudo service apache2 restart
