 * Hi,
 * Just updated to 2.0 and received this warning from WP:
 *     ```
       Hi!
   
       Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site and notifies you with this automated email.
   
       In this case, WordPress caught an error with one of your plugins, Heartbeat Control.
   
       First, visit your website (https://mysite.com/) and check for any visible issues. Next, visit the page where the error was caught (https://mysite.com/wp-admin/admin-ajax.php) and check for any visible issues.
   
       Please contact your host for assistance with investigating this issue further.
   
       If your site appears broken and you can't access your dashboard normally, WordPress now has a special "recovery mode". This lets you safely log in to your dashboard and investigate further.
   
       https://mysite.com/wp-login.php?action=enter_recovery_mode&rm_token=412sVpQy etc 6&rm_key=bTO1Yg etc
   
       To keep your site safe, this link will expire in 1 day. Don't worry about that, though: a new link will be emailed to you if the error occurs again after it expires.
   
       Error Details
       =============
       An error of type E_COMPILE_ERROR was caused in line 152 of the file /home/mysite/public_html/wp-content/plugins/heartbeat-control/vendor/webdevstudios/cmb2/init.php. Error message: require_once(): Failed opening required '/home/followth/public_html/wp-content/plugins/heartbeat-control/vendor/webdevstudios/cmb2/includes/CMB2_Base.php' (include_path='.:/opt/alt/php72/usr/share/pear')
       ```
   
 * I tried hitting admin-ajax and it just returned a ‘0’ on a blank page.
 * Anything to worry about or amend?

 * Hi there,
 * It seems to be an issue related to OPCache.
 * Can you please check if you have OPCache on your server? If so, you will have
   to purge OPCache to fix the issue.

 * Hi,
 * Please note that OPCache isn’t related to your web server: Apache, NGINX or Litespeed.
 * It’s related to your PHP configuration. The issue you have is mandatory related
   to OPCache. You have an old file which try to load a file which doesn’t exist
   anymore.
 * If you want a quick solution, it will be to totally delete Heartbeat Control 
   and re-install it.
 * Best
