I have the same issue and have tried Firefox and Chrome browsers with the same issue. The main issue I am seeing is we are trying to use CKEditor or TinyMCE which require the page to be in standard mode. This worked up till sometime in the last year.
@Terry31459325f5az , this thread is 17 years old. That amounts to a number of generations in software terms.
In fact, ColdFusion has had 8 major-version releases since 2006. Hence, I would suggest that you start a new thread of your own.
