HTML type is not enabled for Hummingbird

HTML compression is not enabled and the following rule was added to the .htaccess file:
<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/html
</IfModule>
But I am still getting this error:
Gzip is not working properly:

- Your server may not have the "deflate" module enabled (mod_deflate for Apache, ngx_http_gzip_module for NGINX)
- Another plugin may be interfering with the configuration
If re-checking and restarting does not resolve, please check with your host or open a support ticket with us.
