RCMS Pro products are encoded by IonCube PHP Encoder and you need IonCube loader is a requirement to run our products. If your web hosting provider lets you have your own dedicated php.ini file then I recommend you install IonCube using this method http://www.rcms-pro.com/interactive/Server_Related/p2_articleid/10. But if you don't prefer that or have root access to your server then you may follow this installation guide.

• Root Shell Access to your server.
• Download the loader suitable for your server from here: http://www.ioncube.com/loader_download.php.
• Unpack the binary file by using this command tar -zxvf ioncube_loaders.tar.gz (Change the ioncube_loaders.tar.gz to the file name appropriate for your server)
• After extracting it will create a folder called ioncube. Now use this command: cd ioncube
• Copy ioncube-install-assistant.php to a web directory by typing this command cp ioncube-install-assistant.php /home/userdirectoryhere/www
• Visit that file by going to http://www.yourdomain.com/ioncube-install-assistant.php.
• And you should see something like below (depends on your server and configurations):

PHP Version 4.3.3
Operating System Linux
Threaded PHP No
php.ini file /usr/local/lib/php.ini
Required Loader ioncube_loader_lin_4.3.so

• Go back to where you extracted the ioncube folder by using cd..
• Now move the ioncube folder in a safe and permanent location by using command: mv ioncube /usr/local
• Now edit the php.ini file for example: pico /usr/local/lib/php.ini
• Look for [zend] by typing CTRL + W and typing [zend]
• Paste the following line under [zend], zend_extension = /usr/local/ioncube/ioncube_loader_lin_4.3.so
• Press CTRL + X, type Y and press Enter.
• Restart the server by typing: /etc/init.d/httpd restart
• Your installation is done .

*If you have Zend Optimizer installed then put the ioncube loader line before the Zend Optimizer line, else you will receive any error.
