Thanks for the super fast reply, wow!
Yes, I did press the crop button and I checked the modal-dialog and it does show the correctly cropped images. Yay! Unfortunately they are not shown on the front-end. I’ve tried various browsers and also force-reloaded the pages – but the old thumbnails are shown…
This is the link with the gallery that shows the wrong cropping. Maybe you have another suggestions? Thanks so much already!
