I’ve found that customized themes tend to be where the issues with avatar cropping start, and am guilty of this myself.

It usually comes from one of two things.

1. A JavaScript error in something you’ve tried to add is causing the JavaScript for the crop tool not to function.

2. Applying a CSS style to your theme that also ends up encompasing the crop tools position, so that it is out of the visible area of the photo container.
