I am not able to complete the challenge in the 'Getting Started with Chatter' trail.

Within the challenge I need to update my profile picutre, it goes through all of the correct steps and I am able to Save but the picture doesn't load - same with changing the picture for the group. 

The error I receive is 'Challenge not yet complete... here's what's wrong: One of the following Chatter profile details has not been set: Photo, About Me, Title, City. Make certain you have changed all of these from their default values.'
