My YouTube page has suddenly disappeared.

On whatever browser you are uaing make sure cookies are enabled and also flash (both under browser settings) then if you have any plugins adblock, ghostery, etc... Pause or disable them temporarily (either settings menu or click on plugin icon depending on browser) and than refresh the page/reopen browser. Of still not working try another browser (Chrome, Firefox, IE). If still not working go to the Adobe Flash website and download and install the latest Flash version.

If after all this you still can't get videos playing make sure all the latest windows updates are downloaded via windows update (control panel) and the restart the computer. Good luck.

Do you have the latest version of Adobe Flash Player.. And how does it not open does it show an error or is it a blank page.?

make sure ur audio driver is update to the latest version and also u have the latest version of adobe flash player (10.3.183.7)..

Videos on YouTube are streamed through Adobe Flash player. If you're having trouble playing videos on YouTube, we suggest you install the latest version of the Flash player.

Please follow these steps to upgrade to the most recent version of Adobe's Flash Player:

1. Before installing Adobe Flash, you will need to first uninstall any older versions you currently have running on your computer. To do so, download Adobe's official uninstaller here. Make sure to select your correct operating system, and then "Uninstall Flash."
2. Now that you've uninstalled the older version of Flash, follow Adobe's instructions for reinstalling the most recent version. The download option is on the right-hand side of the page.
3. Once you've downloaded the file, please exit your browser first, and then install the upgraded version of Flash to you're computer.
4. Finally, open your browser again and go to YouTube. You should now be able so successfully watch videos!

If the instructions above don't resolve the issue, please also try the following:

1. Temporarily disable popup blocking software installed on your computer to test.
2. Allow YouTube.com as a trusted site in your Firewall software.
3. Ensure other applications like Quicktime, iTunes, Real Player, or Windows Media Player aren't set as the default streaming application, as this might affect the video player.
4. Make sure your computer is set up properly for Flash by checking out Adobe's Advanced Troubleshooter here.

Hi, the videos may not play if the Adobe Flash Player in the computer may corrupt or not updated to latest version. Please download and install the latest version of the Mozilla Firefox and then download and install the Adobe Flash Player. Please restart the Mozilla Firefox and visit the Youtube. Now the Videos should be playing.

Please search in google as Mozilla Firefox and Adobe Flash Player to get the download link for the Mozilla Firefox and Adobe Flash Player.

Go to firefox.com and download the latest version of their browser. Firefox works seamlessly with YouTube but you also have to have the latest version of Adobe Flash Player.

Just go to http://get.adobe.com/flashplayer/otherversions/ to download

You need to install adobe flash player from here:
Click on get the latest version

Accept ADOBE DLM
And the licence agreement.

Good luck.

Is it only youtube or any other web site? Any errors. Try to install flash and shockwave from Adobe and maybe some codec with windows media player or quicktime. Sometimes they are required by some pages of youtube.

If you keep getting "HELLO, YOU EITHER HAVE JAVASCRIPT TURNED OFF OR AN
OLD VERSION OF ADOBE'S FLASH PLAYER....GET THE LATEST FLASH PLAYER":

don't bother downloading and re-installing the latest Flash over and over and over again.
You will get absolutely nowhere doing that, because that is only adding to the problem.

There can really be only 3 possibilities:
→ something's wrong with YouTube
→ something's wrong with your cache
→ something's wrong with Flash 10

YOUTUBE:
¯¯¯¯¯¯¯¯¯
Your problem could fix itself in a few hours, or the next day,
because YouTube actually shuts down a lot of their servers
every day without telling anyone, (in order to update things).
On those occasions, it's really YouTube's transmissions of
"JavaScript" and "Flash" which are poor, not your reception
of it. This creates "time-out" or "run-time" errors, giving that
message. You can sometimes fix this by either: hitting "F5",
clicking "Refresh", or clicking "Back"/"Forward". PLEASE VOTE.

CACHE:
¯¯¯¯¯¯¯
If by the next day YouTube is still showing you that JS&FP
message, maybe your "temporary internet files" and cache
memory are full and cannot take anymore. As such, videos
can't even begin to buffer.

"Temporary internet files" are 1000s of little bits and pieces
of websites put on your hard-drive. They'll stay there forever,
slowly plugging up your computer, (like hair in a sink drain)
until you get rid of them. Otherwise, one day your YouTube
will suddenly be "stuck".

Because your computer now has such little space in which
to "cache" a video, YouTube will mistakenly think that your
JavaScript's "runtime environment" or "buffer overflow" is off,
or that your player is "FLASH 7".

The solution to all that is to first exit YouTube, but not your
browser. After, clear your "cache" of all its "TIFs", "cookies"
and "history". (See below.) After that, shutdown and reboot.

FLASH:
¯¯¯¯¯¯
Watching YouTube vids hasn't changed in the past 2 years.
(Believe it or not, you can still use "Flash 8" if you'd like to).
The newer Flash players are giving many YouTubers plenty
of grief -- particularly since there are 11 different "Flash 10s".
It's nuts that there is 10.0.525, 10.0.576, 10.1.218, 10.2.26,
10.2.54, 10.12.10, 10.12.36, 10.15.3, 10.22.87, 10.23.1, as
well as 10.32.18 now.

Most updates are good for only 1 thing:...Software conflicts.
I've never strayed away from 9.47, and many "flashers" use
9.45 still. Think of them as Windows XP compared to Vista.
Look at what the Asker said after this Best Answer of mine:

If that seems interesting to you, here is the appropriate link:

Note 1: if you've got an "Accelerator", dump it, burn it, rip it,
kick it, trash it, disable it, uninstall it...get as far away from
it as possible. There are "Torrents", "Messengers" and "Ad
Blocks" that also conflict with YouTube.

Note 2: some longer videos may need "Shockwave" to play
properly.

Note 3: if you downloaded Flash, did you actually complete
the process and INSTALL it? If you have Firefox or IE 8, did
you enable their add-ons?
