W3C compliant problem

Hello,

I’m using this wonderful plugin for a while and i’m very happy of it.
Recently I’ve been making a w3c check with the online validator and my website got just 1 error : the <link> element with the plugin css is in the body instead of the header.

Is it possible to modify this in the next versions ? Is there a way I can modify it manually on this version ?

Thanks in advance, you’re making a great job !
