Do You Provide HHVM Hosting Support?

Updated on May 11, 2018

All our environments come with PHP 7 enabled by default but you can switch your site to HHVM in the MyKinsta dashboard. While we still offer HHVM, we no longer recommend it.

HHVM is no longer a stable or suitable solution for high-traffic WordPress sites. HHVM, in fact, was never officially supported by WordPress. And as of May 2017, it’s no longer a part of WordPress core’s testing infrastructure. This has introduced bugs and compatibility issues  (which we have seen first-hand)  with recent versions, including third-party plugins and themes.

Beyond support for HHVM hosting, our PHP vs HHVM benchmarks showed that PHP 7.2 actually performed faster than HHVM. This included tests of a standalone WordPress site, WooCommerce, and Easy Digital Downloads.

With that being said, you can still switch your site to HHVM. But we will be eventually discontinuing support for HHVM as it’s no longer a good option.

Switch WordPress Site to HHVM Hosting

To get started, log in to your account at Select the site you would like to switch to HHVM. Click on the tools section and scroll down until you see the PHP Version section. Select HHVM and save your changes.

Note that the change will take 5-10 seconds to take place. You will receive a notification at the bottom of the screen as soon as it is done.

Important Notices:

  • Not all themes and plugins support HHVM. Please double-check your website to make sure everything is working as expected. Since HHVM switching works on our test environments as well you may want to consider testing HHVM out there.
  • New Relic does not support HHVM yet so we won’t be able to see backend processes if something is slowing your site.
