Unable to Save Form
PermalinkAn invalid form control with name = "ccmCaptchaCode" is not focusable. Failed to load resource: net::ERR_CACHE_MISS
I am seeing this issue in all of my forms.
I also attached a file containing the image of what I am seeing,
Any advise....?

It seems like it is trying to enforce the CAPTCHA that is part of the form itself when you try to submit an edit to the form. It shouldn't.

Basically 5.6.3.2 adds the html5 required="required" attribute to the CAPTCHA and that's what's stopping the update from saving
I never tested going straight to 5.6.3.4.
As mentioned previously it was caused by a bug in 5.6.3.2.
