Class Memcached not found when deploying on sub domain in GoDaddy : Laravel 5.2.37

I got this error:

[2016-06-24 00:48:52] production.ERROR: exception 'Symfony\Component\Debug\Exception\FatalErrorException' with message 'Class 'Memcached' not found' in /home/Myserver/public_html/Laravel/vendor/laravel/framework/src/Illuminate/Cache‌​/MemcachedConnector.php:51 Stack trace: #0 {main}

There is no problem when the deployment is done on root. This issue comes only and only when being deployed on sub domain on GoDaddy.

Anybody faced this kind of issue on sub domain on Godaddy?
