I had an avatar and I went to change it. Now it won't work at all. It says that it was uploaded successfully but when I go to view it, it says that it cannot find the page. Am i doing something wrong? It also won't show on posts. Obviously.

 

after you uploaded it, did you hit the "apply" button at the very bottom of the page?

 

Now I feel stupid. It's amazing what happens when you do things correctly. Thanks.
