Plugin makes problems with images

Since the last update of this plugin and the last update of wordpress to version 4.4.1. I can’t use the function “Add images” to my blog entries. The thumbnails of the pictures doesn’t load so I can’t mark them to add them to my entry. If I deactivate your plugin it works! Perhaps you know what the problem can be? I hope you can understand my german english. 😉
