Hello,
I have the same and exact problem on DNN 7 (after migration from DNN 5).
Is there any solution ?
In fact, when I click on an image in the HTML Editor and I click on the small icon image, I do not have anything displayed in the window (should be the image with parameters). The Event viewer gives the following error:
AssemblyVersion: 7.0.0
