Due to some updates with WordPress and other plugins, the plugin that was managing your avatar has been removed. You will have to re-upload your avatar by going to your profile.
- Hover over your profile on the top right and click on “Edit Profile”
- Scroll down to “Profile Picture”
- Click on the link below the profile picture. It will take you to Gravatar.
- Log in with your AG account and then upload a new photo.
