W3C validation error

Hi,
Thanks for the great plugin. We’ve been using it for years now and it works like a charm 😉
We just have a small issue with some CSS style that the plugin automatically adds in the page, when trying to validate our html. Would you please help us fix this ?

We get this <style type=”text/css”> syntax error :
Error: Element style not allowed as child of element div in this context.
