Fixing Drupal 8 Opcache warning (PHP OPcode caching not enabled)

I’m fairly new to Drupal (Drupal 8) and OPcode caching. I hate to see warnings, and checked with my hosting provider who assured me that OPcode caching was enabled.
I configured my php.ini with the necessary information, and checked that my cache folder was indeed filling up with information from people visiting my site.

Yet the warning: PHP OPcode caching Not enabled

PHP OPcode caching can improve your site’s performance considerably. It is highly recommended to have OPcache installed on your server.
