Yes, the ionCube Loader is by default installed on our servers.

What is ionCube?

ionCube is an encoding tool for developers to protect their PHP code from being viewed, altered, or even ran on unlicensed machines. Prior to encoding, the source code is compiled to bytecode then eliminated. The PHP extension ionCube Loader then reads and executes the encoded files.

Confirming ionCube Loader is installed

To confirm that the ionCube Loader is installed and available, simply check your phpinfo.php page and do a search for ionCube. You should see it listed under Additional Modules.

Hello, I have a Wordpress installed on my page hosted here (, however, recently when I try to login to my wp-admin area, I get this error:

Site error: the file /home/curiou21/public_html/wp-content/plugins/seo-alrp/php/admin/registration.php requires the ionCube PHP Loader to be installed by the website operator. If you are the website operator please use the ionCube Loader Wizard to assist with installation.

Is there any way I can update the ioncube loader to version 5.4 to make it work?

Hello Eva,

In looking at your php.ini file it appears you already have a setting that calls the ioncube_loader_lin_5.4. Did you already have this issue resolved by support or is it still giving issues?

Kindest Regards,
Scott M

Hi Scott,

thank you for your reply. So far I only desactivated the WP plugin that caused the problems, which made it possible to me to login to my WP admin area. However, once the plugin is activated, the same problem appears. I am going to try to discuss with the plugin author about the problem, now that I know there should not be a problem with ioncube loader on our side.


Best wishes,
