Perhaps it's related to the - as the second character in the ID string.

You are right. I fixed this bug in CVS. To fix it on your local installation, open the file plugins/videoplug_plugin/_videoplug.plugin.php and change line 135 to

if( video_ID.match( /^[a-z0-9_-]+$/i ) )

Worked perfectly. Thank you.

You're welcome. :-)

I have exactly the same problem in version 5.2.2.
Replacing the code in the PHP script makes no difference, and when I use the video icon in the 'Simple' tab, I get the message I am using an invalid tag, which is IFrame.

Any further advice, please?
Thanks.

Hi @vlaanderen,

I guess you're trying to paste the entire URL into the dialog of the video plugin. In that case, as explained on the first section of this page: http://b2evolution.net/man/how-to-add-videos-1, you need to paste only the video ID (see image above).

The second method explained in the same page is more adequate when you have the direct URL to a video file instead of having it hosted in youtube, vimeo, etc. It also requires to enable iframes support and set security check to basic in the blogging permissions of your user group (http://b2evolution.net/man/blogging-permissions).

So, as you can see, it's way easier and safer to use method 1.

Regards!

Thank you so much, mgsolipa.
That did do the trick, but it was quite easy to miss (I did :) ) that only the ID had to be entered.
Anyway, problem solved, thanks again.
