First I went to Filezilla, and found where all the avatar images were.
The remote site path looked something like this:
/public_html/images/avatars/upload
This was wrong.
Next I went to my cpanel of hostgator, then into file management and found a longer path and I entered this:
home/myname/public_html/images/avatars/upload/
Also wrong.
Then I tried
/home/myname/public_html/images/avatars/upload
This was correct.
