The ionCube loader PHP extension is disabled on all hosting servers by default. If your website needs the extension you can activate it from your Site Tools -> Dev -> PHP Manager -> PHP Extensions tab -> pencil icon next to the ioncube entry.
Once the extension is loaded, if you want to check the version of the ionCube loader, create a PHP info script on your account and access it from your browser. For example, create a file called serverinfo.php in the public_html folder of your account, using File Manager and place the following content in it:
<?php phpinfo(); ?>
Access the file in a browser (e.g. http://yourdomain.com/serverinfo.php) and it will show you the entire configuration of the PHP interpreter as well as the ionCube loader version.
