First of all thanks for this awesome plugin, just by installing ti and enabling it I'm seeing a lot of benefits for my site, that's simply awesome.
I'm just having a couple of small issues (nothing is broken so far so I think it's minor).
The Bulletproof Security plugin is saying that the code W3TC adds to the htaccess file is not added and I should just deploy it again, I have done it several times, but the code is not added, not sure why or how this affects the plugin.
On another note, I'm using MaxCDN with W3TC, the benefits are awesome but for some reason I'm not able to pass the "Test NetDNA", it says my ip is not whitelisted, but it is (it is still working tho).
Lastly on the browser cache tab I enabled the expire headers, but Yslow claims there is no such thing in the page. It's a bit confusing.
Overall I'm happy with the plugin and if someone could tell me why those things show up I would be truly happy to give a 5 star ranking. :)
