gzip is not working properly

Hi, my gzip compression is not working propelly:

- 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.

I have chcecked that with my hosting support, mod_deflate is allowed and they have said, that I should add MIME types (text/html, text/plain, atd.) in the .htaccess.
Your code has been saved into .htaccess.

I have opened a support for you for three day, but be careful, please.
