No HTML code in Yosemite OS X

I take it you me safari on Yosemite.

As with any software or system, none can bet on support for something not out yet. Yosemite is only available to developers as a beta right now.

I am sure BC have had a look at it, tested BC on it, but if there are safari bugs, apple will fix them. You should not use it and treat it as production.

Newest Safari update (Version 7.1 (9537.85.10.17.1)) on Mavericks. 

Errors such as the following are popping up:

WYSIWYG editor is broken.   Everything's a mess.
