Shortcodes are not working properly

I had a similar problem with the custom tabbed boxes. In my case, I had been trying to use additional shortcodes from another shortcode widget inside of the tabbed boxes. Until I figured that out I also thought it might have been following the addition of a new plugin I installed that somehow conflicted with the shortcodes plugin. I deactivated the most recent plugins I had installed to see if that removed the conflict. That problem can also occur if you have lost a [ or messed up the code on one of them or forgot to close a tab. Hope that helps.

Yes, YouTube and Vimeo codes produce broken results. Both show videos but both hide all the navigation elements. If with YouTube code you can double click on the video and it will open full screen with navigational elements, then Vimeo video either plays or stops on clicking.
