The ionCube loaders PHP extension is installed on all of our shared hosting servers by default. If you want to check the ionCube loaders version, please create a PHP script on your account with the following content:
<?php phpinfo(); ?>
Then access the file via your browser and it will show you the entire configuration of the PHP interpreter as well as the ionCube loaders version.
If you have a script that gives an error about missing ionCube loaders, please make sure you are not using any custom php.ini files. When you have a custom php.ini file, it overwrites the global PHP settings and this may result in a missing ionCube loaders script error.
