I'm a writer for symbianworld.org and it seems that embedding videos like youtube and vimeo doesn't work. I tried to clear cache, history and all to two of my browsers, firefox and chrome with latest version same with flash player. After that the vids aren't still working.
On the Visual tab I can see a flash video box (same on vimeo vids), but when I preview it, then there's no any video, same when I publish the article the videos don't show and the embedded code is gone when I came back to edit the post.
I'm just a writer and I don't have a WP on my pc. But on the other site I tried to post with embedded videos like in thenokiablog.com (wp also) and a mobileworldinnovation.com (blogger) it seems the videos are working. I'm only having problem with the current site (symbianworld.org)
Is there a need for a plug in to install that should my admin do? But why it only happened to this site with wp.org.
Here's what appeared on my Visual Tab and HTML : http://img62.imageshack.us/img62/3403/wordpresserror.jpg
