SOLVED: The file Cache Storage is not supported on this platform.

Upgrading or newly installed Joomla CMS? You might find this error: The file Cache Storage is not supported on this platform. We have your easy fix.

More than likely this is a permission error originating from your user and the user group that the Joomla CMS expects. In our experience Joomla is looking for www-data to be the owner of the administrator/cache and cache folders and that they are writable (typically 755 permissions by the group owner). A quick command in the terminal will likely fix your woes (on Ubuntu 16.04 running a Nginx LEMP stack):

sudo chown -R www-data:www-data /var/www/html

We are simply telling our server that any and all folders within the html folder should be owned by the www-data user within the ww-data user group. Simply refresh your pages and viola!

A freshly install Joomla 3 CMS (front end, default template).
