i get it after i upgraded to latest nui.

Are those all of your addons? Because Ace2 is actually a framework for other addons, but not nUI (or Swatter iirc). Anyway, that's an Ace2 error.

Yeah, it's possible that ace2 is looking for ChatFrameEditBox which of course doesn't exist anymore.

So,

1. Look to see if Ace2 has been updated.

2. Maybe it is an addon using ace2 that is borked in which case turn off all addons except nUI itself and slowly add your addons back in one at a time and see which one triggers the error. Make a note and continue after ( disabling that one of course ). Once you have a list of addons that cause the error or others, see if there are updates for those or at least comments on the download page that they are being worked on.

3. Once you have either removed the addon or incorporated the fixed version it should stop the errors.
