I'm trying to add a slideshow onto this article but when i go into classic mode (visual) it keeps telling me "Rich text editing has been disabled because the page contains complex code.", i tried adding a slideshow through the source editor but it just screws stuff up and i don't know where the complex code is so i can take it out and use visual editor. Can anyone help me?
