WHMCS 500 error after upgrading to EasyApache4 – Ioncube error

After upgrading to EasyApache4 and then running a Softaculous upgrade of WHMCS there are a couple of things you need to do to ensure WHMCS functions as expected.

Step 1

Ensure you are using the latest version of PHP (v7) and enough memory is allocated to PHP. See our post here

Step 2

Ensure you have the Ioncube loader for PHP 7 installed

In WHM go to Software -> EasyApache4 -> Customize -> PHP Extensions

Search for php70-php-ioncube6 and enable it -> Click next


Step 3

You will then move onto the review screen at which point click on the “Provision” button on the bottom left of that screen.
