Chevereto Users?

[WP V0RT3X]

Hi guys, I've already asked in the Chevereto Community but sadly without response, maybe not many IPS users are really active out there.

After integrating in 4.7 the upload button is displayed, but the problem is nothing is inserted in the textfield at all. I can click the button, the popup opens, I upload my pics and then the popup closes, that's all.

Tested on 2 completely different sites with the same default plugin code (one is a fresh test installation without any other modifications). To make sure I tested exactly the same code with another editor (Froala, XF2), where it works fine.

Is there some kind of special setting to make pup.js work with CKEditor?
