You are right about the Easy Rotator being the issue. This is the error I get when I am on the Ditty News Ticker edit page:
Uncaught ReferenceError: edCanvas is not defined post-new.php:998
I'm guessing the script for that plugin presumes there is a content editor on the page, and since there isn't one with DNT, it's triggering an error because it's trying to use reference that object. There isn't anything more I can do for it, but you should contact that plugin's author and let them know about the error.
That's the only error I see right now. But, it is possible there is still one in the theme that's just not being triggered yet, since the other plugin is erring out first. If you can get the author to fix that issue I'll have a look at your site again if things still aren't working.
