I'm helping a friend with her WordPress site (I semi-admin it) and I noticed that when people write comments there's a broken image-link on all comments.
The only image that's supposed to be shown there is some gravatar one I think. And looking at the page source and clicking on that image link does lead to a functional page.
The image that it seems to want to show is: http://0.gravatar.com/avatar/8a378454f7dab50cce35b2e08fe71bee?s=68&d=http%3A%2F%2F0.gravatar.com%2Favatar%2Fad516503a11cd5ca435acc9bb6523536%3Fs%3D68&r=G
Is this something some else has noticed? I'm using the theme Twenty Eleven version 1.3.
Thank you in advance.
