TinyMCE error

Beta
#1

This popped up in the browser console when I entered HTML mode in a text field:

TinyMCE Error TypeError: can't access property "getRng", e is undefined

I wasn’t able to recreate. It sounds like a race condition though and might not happen everytime. Was this in Chrome?

#3

It was in Firefox.

#4

It’s still happening in beta3. Switched from HTML to Rich Text and the same happened.

#5

I didn’t update anything related to this yet. I actually get a different error that I was able to remove, but let me know if you still have this same error in beta4. You are still able to edit in Rich Text mode right?

#6

Ok, will do. Yes I can still edit in Rich Text mode.
