Post Settings Menu

Hello,
I’ve got an issue with the last update.
The Post widget settings have disappeared.
When i disable ECS the posts settings works again.

I’ve got this message in the console everytime i click on the post widget

underscore.min.js?ver=1.8.3:1 Uncaught SyntaxError: Unexpected token ‘{‘

What could i do ?

Thank you
