i am struggling with the same problems. You solve the first problem with element inspection in chrome browser. Push the red cross in the right and you see the problems on your site.
I also have the second problem on my dashboard and i dont know how to solve that.
It's because there's a iframe in that page and it's not your site problem.
Basically I frame is used to display webpage into another webpage.
