There is too little information to be completely sure, but usually this error occurs when WordPress cannot find the graphic library which should be installed on your server. So you should check with your provider to see if Imagick and/or GD are installed. You can also add this little snippet of code in your functions.php … Read more
WordPress “crop” doesn’t literally mean crop. As in take an image and cut out this precise portion of it from specified point. What it roughly means is: resize image to fit as well as possible, then crop parts that don’t fit. In effect this meant that results are affected by ratio both of source image … Read more
It looks like the select and crop functionality is currently only used in the WordPress Customizer.

Currently, WordPress core image handling/thumbnail creation does not perform zoom-crop. If you need an intermediate image size to be created explicitly, you will need to ensure that you upload an image with equal or larger dimensions as the intermediate image size.
In your theme’s functions.php file: /* register new image size * 200px wide and unlimited height */ add_image_size( ‘wpse73058’, 200, 9999, false ); In a template or the like: if ( has_post_thumbnail() ) { the_post_thumbnail( ‘wpse73058’ ); }
