Both the user avatar for the main site, and their blog avatar wont allow users to press "change avatar" when you click "change avatar" it brings you to the 'You do not have sufficient permissions to access this page.'
The plugin is installed and activated. The default avatar is displayed for both the user and blog when you visit profile, but the permissions seem to block access to change.
I have already tried to download a user role editor plugin to adjust the permissions for users etc. But the capabilities do not list upload avatar, so i can not even tell if a user has sufficient permissions.
