YouTube Bar Missing IE

WITH INTERNET EXPLORER 8

On the YouTube page, you need to go to "page" > "compatibility view" > a box will appear above > click on OK, and that's it.

I just did it in "Tools/Internet Options/Delete" and cleared it with CCleaner as usual. No change.
I reinstalled Java, Adobe Flash Player, and installed the new version of Internet Explorer, just in case, but nothing either.
Finally, after formatting, everything returned to normal.

Update
Many internet users have reported this issue to YouTube. Therefore, they created a "special unit" in the FAQ that explains how to fix the problem. You just need to uncheck a box in the Adobe Flash Player settings that appear when you right-click on a video. Since then, no more disappearing bar and the image is back :D

Armageddon was yesterday - Today, we have a serious problem ...

Hi,

Check if Java is up to date?
Is Adobe Flash Player also up to date?
