I don't get any response when I click on buttons on Youtube.

These buttons include:

Drop-down menu next to Subscribe
My channel button on the upper right
Language chooser at the bottom of the page
Three selections (All activities, Subscriptions, Recommended, (translation might be off since my page is in Danish)) on the Home page
Thumbs up/down buttons on both video and comments
Reply button
Your reaction? button
Share button
Add to button

and I'm sure there's more I've missed.

What can I do to solve this problem.
