“Accept YouTube content” button doesn’t display properly

Hi,
Thanks a lot for your great plugin. We really appreciate it.
We have a small issue with the “Accept YouTube content” button: the red color of the button doesn’t appear so the label of the button is not readable.
In my understanding, it comes from the theme we are using (Vantage Premium).
I’m not good enough in CSS to tell if I should submit this error to you or to the “Vantage” support.

Thanks for your help
Kind regards
Philippe
