I'm using one of these wordpress tubethemes and used to be able to play the videos that I posted. When trying to watch them now I either get a blank page, a video window which turns into a blank page when clicking play, or just the code for the video - depending on which code or plugin I'm using.
When this happens I post the code using "custom fields". When trying to add the code into the post itself using html view however the video shows up properly.
So I wondered if anyone else had experienced this? Or does anyone know how to fix it?

My theory is that it stopped working when I upgraded wordpress..
