I got this error:

Hi,
I got 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

-------------------
I checked my dedicated server, in WHM the settings already turned on. I am using Apache4. htaccess already have the code. i already checked.
