title: failed upgrading ioncube loeader for php 7.0 and 7.1 in plesk
body: <p>I have installed <strong>plesk onyx</strong> in my ubuntu server plus <strong>php v7.0 and v7.1</strong>. When I tried to install <strong>WHCMS v 7.3.0</strong> he told me that I have old ioncube loeader version and I need to make an upgrade to continue the installation so I followed that tutorial : <a href="https://support.plesk.com/hc/en-us/articles/214527125-The-IonCube-loader-is-not-available-for-Plesk-PHP-7-1" rel="nofollow noreferrer">https://support.plesk.com/hc/en-us/articles/214527125-The-IonCube-loader-is-not-available-for-Plesk-PHP-7-1</a> 
  and this is the version of php v7.0 and v7.1 : </p>
