i installed this plugin yesterday. I also use maxcdn and my website is way faster then before.
The only problem is that after i installed the plugin pingdom says that i have to remove query strings from static resources.
I searched for it on the internet and i saw that i have to uncheck the box : Prevent caching of objects after settings change.
The problem is that i unchecked this box but i dont't see any results. Pingdom still gives the same grade.
Have can i fix this?
