Error After Upgrade to PHP 5.6

[kridaweb]

I have a dedicated server and use the sentora as its control panel. I have installed WHMCS on my server but it can not run because there is no IonCube, then I add IonCube on my server without any constraints. After IonCube I added it still can not be used and error 500 or internal server error, after I browse the latest version of WHMCS requires PHP version 5.5 or 5.6. Then I tried to upgrade PHP to version 5.6 and success. But when in ssh I typed "php -v" why the result like the following:

Can not load the ionCube PHP Loader - extension already loaded
PHP 5.6.30 (cli) (built: Jan 19 2017 08:09:42)
Copyright © 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright © 1998-2016 Zend Technologies
    With the ionCube PHP Loader (enabled) + Intrusion Protection from ioncube24.com (unconfigured) v6.0.9, Copyright © 2002-2016, by ionCube Ltd.
    With Suhosin v0.9.37-dev, Copyright © 2007-2014, by SektionEins GmbH

At the top line there is an error Can not load the ionCube PHP Loader. How to handle it? Additionally error also occurs when I want to make the mysql username always happen Internal Server Error. How to resolve the error without having to re-install my server or how to restore php to version 5.3 or 5.4 according to the standard of sentora.

Please help. thank you

Check php.ini if you don't have multiple includes.

How did you install ionCube may be you should remove it and install it back after php upgrade.
