I have a multisite running but I seem to have broken the ability to change a user's Avatar.
I no longer see the function in the Admin window and the functionality on the profile page is broken too - you can upload an image but you cannot see the images for cropping.
In regards to the Admin pages, in the past I could set the avatar by either selected an optional Gravatar Avatar or upload an image... but that whole functionality is now missing.
One last remark, the avatar image on all the network (subdomain) pages are not working correctly. In other words, they are not showing up. Instead the default mystery man avatar show for all the users.
Any help would be greatly appreciated. Thanks.
