 * Hello,
 * I have the plugin activated but “It seems your server setup does not support 
   headers in .htaccess. You should either fix this (install mod_headers) or deactivate
   the “Enable direct redirection to existing converted images?” option. Otherwise
   the Vary:Accept header will not be added and this can result in problems for 
   users behind proxy servers (ie used in larger companies)” error.
 * I contacted the server company and it was stated that mod_headers is active on
   the server. Although mod_headers is active, I still get this warning and I can’t
   use the plugin unfortunately 🙁
