Issues with humming bird

I have expires on my server as per my host but i still get this.
See screen shot of all plugins, nothing should be an issue. I even disabled itheme security to test. https://drive.google.com/file/d/0B0WGFex1JOUcVzkxMjdnaWctY1E/view?usp=drivesdk

I also have an issue with cloudflare, they do have their own so not sure if that is a problem. Its blank in humming bird, not sure what i should have to do to set it up.

Dashboard is installed not sure what else i am supposed to do for access.

Browser Caching is not working properly:

- Your server may not have the "expires" module enabled (mod_expires for Apache, ngx_http_headers_module for NGINX)
- Another plugin may be interfering with the configuration
