GZIP – Your server may not have the “deflate” module enabled

Hello @darrenchu,

hope you’re doing well and thanks for reaching us! ??

Can you also double check with your hosting provider that the
zlib.output_compression
is enabled?

If it’s not, then turn this ON and re-check status in HummingBird -> GZIP compression.

Warm regards,
Dimitris

Hi Dimitris,
Tks for the quick response!

I turned on zlib.output_compression from a setting within Cpanel, and it allowed my domain to pass the checkgzipcompression website (https://checkgzipcompression.com/?url=https%3A%2F%2Ftradablepatterns.com%2F).

However, from the Gzip Compression page of your plugin, I still see the same error as before:

Gzip is not working properly:
– Your server may not have the “deflate” module enabled (mod_deflate for Apache, ngx_http_gzip_module for NGINX).

From https://gtmetrix.com/, gzip seems to be working for most of my site files, but still scores poorly w/ a E as a result of three 3rd party plugin files not compressing.

The gzip test on https://nixcp.com/tools/gzip-test/ says my domain supports gzip.

When I run tradablepatterns.com through https://whatsmyip.org/http-compression-test/, it says: An Unknown Error Has Occurred

Let me know if you have any other ideas.
Tks again!
Darren

@darrenchu,

Please don’t forget to click “Re-check status” button once you make changes to your configuration. I have run a remote check and Gzip compression is working fine, Hummingbird should not be showing this error. Maybe it’s a cached version of the error from your host?

Best regards,
Anton

You’re right Anton!
It appears the host had cached that file…after doing another Recheck status just now it shows GZIP works now!

Tks again,
Darren

@darrenchu,

Welcome! I will mark this thread as resolved. If you have any more questions – fell free to open another thread.

Best regards,
Anton

Hi there. My GZip isn’t working for Javascript and CSS. Both “Filter” and “Deflate” are enabled in Plesk. Can’t seem to get the compression to work.

My .htaccess looks like the following:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

Hi @raymundo824,

In Plesk you need to add the Nginx configuration to the Nginx settings page in your control panel.

Best regards,
Anton
