What does this plugin do?

It speed-up page load times and improves website scores in services like PageSpeed, YSlow, Pingdom and GTmetrix. It will remove any query strings from static resources like CSS & JS files, enable GZIP compression (compress text, HTML, JavaScript, CSS, XML and so on), add Vary: Accept-Encoding header and set expires caching (leverage browser caching).

Any specific requirements for this plugin to work?
  • GZIP compression should be enabled on your web server (Apache?). If not then you can ask your web hosting provider.
  • .htaccess in your WordPress root folder must have write permissions.
What if I get 500 Internal Server Error?

If you get “500 – Internal Server Error” after you activate the plugin, Follow the steps below:

(1) Login to your FTP or open File Manager (ask your hosting provider)
(2) Go to the WordPress installation folder and then wp-content/wp-performance-score-booster folder
(3) Copy .htaccess.wppsb file
(4) Now move back to WordPress installation folder and Rename the .htaccess file (to something like .htaccess.bak)
(5) Paste .htaccess.wppsb file (copied from step 3) and rename it to .htaccess

That’s it! Your site should be up now.

It’s maleware and now I can’t remove it

I highly recommend staying away from this plugin, I can not delete it in dashboard, and when I do in the FTP, it deletes my entire plugin folder and I can no longer access my plugins as it just forwards to the homepage.

But then even after accepting that I couldn’t access my plugin page, it reinstalled itself meaning there is a rootkit in my site now.

Big red flag!

Great Site-Speed tool

Works very well on Avada 5.3 but does not resolve “Vary: Accept-Encoding” header:
Do you have a fix for this?
Using this plugin sent my Site speed in Pingdom.com from 60 to 86.

I will be very appreciative of further assistance in the Vary: Accept-Encoding” matter.

It does the job but now conflicts with the Divi theme

It does what it says it will do, but I can’t give it anything more than one star because it breaks part of the Divi theme I am using, and therefore is unusable.

I get errors when I am using the Divi Visual Builder. Things don’t load, and parts of this plugin break it.

Not working at all

It does absolutely nothing for me. Maybe it’s because my site runs on NGINX, but the plugin really doesn’t improve anything. It doesn’t make it worse either, just does nothing but having a huge full page ad for the developer’s paid services
