To figure what the problem is I decided to start a new extension with just the CanvjasJS library loaded and a basic example of theirs that comes with the download. What I discovered is that it works fine until the version 2.0.2 but after that I just get a blank screen, with no error or failure in any part.
If anyone could help me in this mistery I would appreciate it very much,
