I installed this plugins and after hours of configuring I realized that my theme already supported avatars so I kept my theme how it originally was. But I got it working with no problems. I created a testuser and successfully added an avatar.
However, I tried to add an avatar to my admin account and it shows up as a blank square. When I right-click on it, the url is a gravatar domain. The test user's avatar is also the same now.
Any ideas?
