How to fix the garbled text in my text editors? When editing my nodes all of my saved data is displayed garbled. This is the warning I get on my node/edit pages: "Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check http://xhr.spec.whatwg.org/."
The other odd part is that the contents of the database field and the contents of the output are correct. Just the contents of the text editor is garbled.
How can I fix this?

UPDATE: I have another content type that has a file field, and I have some pdfs loaded in those fields and those pdfs are the ones that are showing up in my text editor. Does anyone know why that would happen?
I had the exact same issue with aGov distro. I had to swapped from ckeditor module to WYSIWYG module + ckeditor lib.

That fixed the issue with ckeditor. However, today I got the garbled text again while having batched processes running which preventing them to complete. Thinking back, I realised the problem started when I installed Devel themer &amp; simplehtmldom API (7.x-1.12). Uninstalling simplehtmldom fixed the issue for me.
