BuddyPress Social Theme Avatar


I tried changing the avatar picture for a users profile but it doesn't work..
When I upload an image I'm taken to a page that asks me to crop my new avatar image but the image I uploaded doesn't show up.. All I see is 2 question marks... I click crop image then I'm taken to another page that says "There was a problem cropping your avatar, please try uploading it again".. I tested all required image formats (jpg, gif, png) and different image sizes incase this was causing the problem..

Why isn't this working? Can someone please help me fix this problem..I'm new to this website and recently downloaded the social theme and was expecting everything to work fine...
