Re: avatar cropping: after upload, image and cropper don\'t appear, fails
This worked a treat for me!
If you need to find your “Full URL path to files” you can find your DOCUMENT_ROOT by using phpinfo(); and adding “wp-content/uploads” to the end.
e.g:
Store uploads in this folder “wp-content/uploads”
Full URL path to files “/home/ACCOUNT/public_html/wp-content/uploads”
How can I create a phpinfo.php page? Try this link:

Be aware that copying the code directly from @gian-ava will copy the wrong type of single quotes as @shaista points out above.
To check that your image is being uploaded take a look in /public_html/wp-content/uploads/group-avatars on your server
