Hi,
I'm having the same issue in one of my plone sites.
What conten type are you trying to edit?
I get the same javascript error when editing an Event after intalling collective.venue.
Strange thing: in another computer, the same buildout, with the same packages installed, doesn't give this error.
Versions:
Plone 5.1rc2 (5109)
CMF 2.2.12
Zope 2.13.26
Python 2.7.14
Hi,
I think my solution is nothing you can work with 
I doubled all <script> tags in the Meta-section - after clearing that, all works as expected... sorry
From the screenshot, this looks like a javascript error.
If it is difficult to find out how to fix it, it can sometimes help to install and / or uninstall an add-on that registers javascript and maybe disable / enable the theme (?)
