Title: GZIP compression does not work with Cache System enabled Last modified: March 27, 2018 --- # GZIP compression does not work with Cache System enabled * [cmilliken](https://wordpress.org/support/users/cmilliken/) * (@cmilliken) * [8 years, 2 months ago](https://wordpress.org/support/topic/gzip-compression-does-not-work-with-cache-system-enabled/) * [https://checkgzipcompression.com/](https://checkgzipcompression.com/) does not work for testing, don’t even bother with it. My service provider uses [http://www.gidnetwork.com/tools/gzip-test.php](http://www.gidnetwork.com/tools/gzip-test.php) and it works just fine for testing GZIP compression. I verified the headers also using the Web Developer plugin for Firefox. * After finding all of this out, I was able to verify GZIP compression was working on my server, and traced the problem back to WPFC. I tested various settings in WPFC, and I discovered that with Cache System disabled, GZIP compression began to work. I flipped this switch back and forth, on it fails, off it works. * If this is how it’s supposed to be, there should be a warning when both are selected. If they’re supposed to work together, then your plugin is broken. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fgzip-compression-does-not-work-with-cache-system-enabled%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 14 replies - 1 through 14 (of 14 total) * Plugin Author [Emre Vona](https://wordpress.org/support/users/emrevona/) * (@emrevona) * [8 years, 2 months ago](https://wordpress.org/support/topic/gzip-compression-does-not-work-with-cache-system-enabled/#post-10120466) * There is no gzip warning on gtmetrix and google page speed tool. * Thread Starter [cmilliken](https://wordpress.org/support/users/cmilliken/) * (@cmilliken) * [8 years, 2 months ago](https://wordpress.org/support/topic/gzip-compression-does-not-work-with-cache-system-enabled/#post-10120505) * Because Caching is currently disabled.

Gzip does not work for html sources. You should contact your hosting provider. * Thread Starter [cmilliken](https://wordpress.org/support/users/cmilliken/) * (@cmilliken) * [8 years, 2 months ago](https://wordpress.org/support/topic/gzip-compression-does-not-work-with-cache-system-enabled/#post-10120668) * Therein lies the problem. I am the hosting provider. Everything has been done to enable this for every mime type, including forcing it server wide. But you’re right, a static HTML page is not being compressed, but everything else is. * [gore.m](https://wordpress.org/support/users/gorem/) * (@gorem) * [8 years, 2 months ago](https://wordpress.org/support/topic/gzip-compression-does-not-work-with-cache-system-enabled/#post-10152501) * May I know why html is not compressed? Is there any possible gzip conflict if I uncheck gzip option in WPFC and instead of that Ill use server gzip?
