I've created a layout page, when I run the page and look at the JavaScript console, I get a 'parentElement' null error message like this:
Uncaught TypeError: Cannot call method 'parentElement' of null
There is no other error message, when I compare this to the other layout pages (which I haven't created) this error message is not displayed.
Does anyone know what causes this error message and what I could be possibly be missing in my layout page.
Thanks
Stephen
