Can't access to Youtube

As you can see, I cannot click on anything. I can use youtube on other browser like google chrome but not safari. I have tried ways like delete cookies and caches. But it only work just after I delete all the cookies and caches. When I restart safari and login my google account again, it just come back to the same problem. Strange enough, this problem only appears in one certain account. Youtube works fine when I am logged out or I switch to other accounts. But the account with the problem is the account I always use and also I am not sure whether this problem will happen on my other accounts in the near future. So I hope someone can have some ideas or solutions about this.

Thank you and pardon my bad English.
