I have been inserting several WordPress galleries (not NextGEN) into my site pages, and up until a few nights ago I had no trouble editing each image's thumbnail.
For some reason when I try to crop thumbnails now, the save button no longer works. I can do all the steps leading up to saving, but then I'll click on "save" many times and nothing happens.
Is anyone else having this problem? Any idea on how to solve it? This feature used to work flawlessly for me.
