I am running PHP Version 5.6 on my Ubuntu 14.04 Server.
/home/ubuntu# php -v PHP 5.6.36-1+ubuntu14.04.1+deb.sury.org+1 (cli) Copyright (c) 1997-2016 The PHP Group Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies
But when I am activating a theme I am getting below error
Your server's PHP version (5.5.9-1ubuntu4.24) is not supported.
This version is old, insecure and slow. Please update it as soon as possible.
Any insights why this is happening?
