Problem with Gravatar profile and related posts

Hello.

I have a problem with Gravatar profile. I’ve updated already mi profile in Gravatar but the widget doesn’t show it in my page, as you can see in the first image.

Another problem are the images in the related posts, they aren’t here. And I would like to know how to remove the line “Leave a comment”, cause I’m using Jetpack’s Comment Form.

If someone could help me, I would appreciate it so much. :slight_smile:

Someone can help me?
