 * In the Hummingbird Cache setting the Purge OpCache option is greyed out. I have
   verified that Opcache is running on the server. Is there an reason this option
   is not enabled?

 * Hi [@cogz](https://wordpress.org/support/users/cogz/),
 * Thank you for contacting us.
 * Please add the following code in a php file(you can name it phpinfo.php)
 * <?php
    phpinfo();
 * And place it in root directory (public_html). Then verify by going to the file(
   e.g. mysite.com/phpinfo.php) and ensure Opcache is turned on for the site. Also,
   can you confirm what PHP version you are current running?
 * Best,
    Jonathan S

 * Hi [@cogz](https://wordpress.org/support/users/cogz/)
 * Sorry for the delay here.
 * It may happen if your hosting disable the opcache_* commands, for example on 
   our hosting.
 * Can you try to create a PHP file **opcache-reset.php**
 * Place this:
 * `<?php opcache_reset();`
 * And try to execute?
 * [https://www.php.net/manual/en/function.opcache-reset.php](https://www.php.net/manual/en/function.opcache-reset.php)
 * And check if the setting will show, if not, please, contact the hosting support
   and check if they have any restriction for the OpCache.
 * Let us know the result you got
    Best Regards Patrick Freitas
