active schema does not support element 'iframe'

T

TR

I have two aspx pages. Both pages have the same DOCTYPE:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

On one, there's an IFRAME and it works without no error. On the other, also
with an IFRAME, I get the error 'The active schema does not support the
element 'iframe'" when in design mode/HTML view.

What could be causing this error in one page but not in the other?
Thanks!
