Certain setting damage header display with Safari and Chrome

Hi Dimitar,

thanks you for this really handy and great plugin that solves a lot of important issues in an easy to use and solid way!

Unfortunately I noticed, that with Hueman theme the two setting default.src and style.src replace my custom header design with the themes default design.

I used * as value.

Any hint on why this did happen would be great!

Many thanks and best
Tom
