Image Crop Editor Not working

Solution 1:

I had the same issue but the problem was missing the GD library, https://www.digitalocean.com/community/questions/installing-the-gd-image-library

To install (Linux/ Apache2):

sudo apt-get update
sudo apt-get install php5-gd
sudo service apache2 restart

Solution 2:

Keep in mind, the interface is not intuitive and it's easy to forget that the [Save] button is still deactivated if you do the following:

  1. Click the crop button.
  2. Select the area you want.

You must do the opposite.

  1. Select the area you want.
  2. Click the crop button.
