CMS's like Drupal 8 strongly recommend that you enable OPcache on your server to speed up page rendering. How does one install this extension if your site is hosted on Media Temple's shared Grid server service?
/etc
folder. If there is a file there called php.ini
skip to step 5php.ini.sample
to php.ini
php.ini
and add the following lines to the bottom of that file:zend_extension=/usr/local/php-7.2.12/lib/php/20170718/opcache.so
opcache.enable=1
I believe this assumes you are running php 7.2.12, so the URL may change if and when PHP is updated on the grid.
