To enable soap on shared hosting servers on our cloudlinux platform.
First log into cpanel.
Click on the option “Select PHP version”
Instead of native (the default) select another PHP version. Check www.php.net for the latest version. As of this writing PHP 5.4 or 5.5 is recommended.
Click save as current.
You will then be able to select ‘soap’ in the modules section and click save.
