Youtube interface problem

Hey,

While I was using Youtube on Safari, it recently changed to this interface.

I already disabled AdBlock for this domain.

I think it may have changed when I downloaded Youtube Centre, although I didn’t change any settings.

All I did was uncheck DASH-buffering, but I already put it back on.

Is there anyone with the same problem, or someone who can help me fix this?

Thanks,

Brent
