Opcode Cache:


This is an entirely new feature. As Opcode is now built-in with the release of PHP7 (which you all should use anyway), this option will be pre-enabled if your version is supported.


Fragment Cache:


Actually, this was probably one of the premium features, I am not entirely sure, but now it’s available for any user.


How to Update:

Don’t worry about anything, have a backup, and click the update.

If you followed our tutorial to get it fixed, its also very easy for you.


In our built the changed the name of the plugin so we could keep track, but we kept the process open so we could get an official update without any hassle. Now our process will pay-off, you could also click just the “Update Now” button. you are all set.

Depending on your server setting you might have to restart your server (apache or Nginx) service. Check the Performance -> General Settings to check the new features. Save. Clean the cache, go to your home page and reload. Check if everything is fine.


Don’t forget to check your site again via whatever you use, we suggested using https://gtmetrix.com/ in our last tutorial. We see really good improvement in our test.



Share your experience, update your site, and always keep your WordPress updated to stay protected.
