I'm trying to crop the thumbnails to replace the predefined ones. It's not working.
here is what i am doing:
1. go to media library and choose an image
2. click "edit image", select the area i want to crop. In the thumbnail setting box, i select "thumbnail"
3. click the crop Icon
4. click save
Finally, the cropped thumbnail doesn't change at all. Now, when I test it in post the thumbnail stays the same, as it was predefined, cropped in the middle of the image.
When i go back to the edit image section, the "thumbnail setting box" disapeared.
thank you for your help
