Hi

Hope someone can help. A day ago, I tried embedding a youtube video into an article and it worked fine. Now suddenly no videos from remote sites work (eg youtube and stupidvideos). My own uploaded videos work but the {youtube}3bd4UJwldQ0{/youtube} (for example) code does not work. In fact, it takes everything written after the code away - it does not appear any more. I have tried everything and this is keeping development of the site back. Please help...

Thanks

Could you post the HTML code you are using?
Did you install any other plugins after it worked?
Did you install/selected a different editor?

Did you read this:
www.joomlaworks.net/content/view/35/41/

?

Thanks for taking time to reply. Last two questions first: No, I did not install another plug-in but I may have published or unpublished several others. No, I did not change editor.
The simple code I put in is: {youtube}yEnW2K-QjTY{/youtube). I use the default editor and this is the html I get:

Pm me acces to your backend please...

Remove everything except:

Did you enable the plugin?

To me it looks like he copied his code from Word or Outlook, looking at all the extra code.
