We have had other members report having this issue and it turns out that there was a compatibility button on the top right of the screen which appeared to be torn in half. Take a look and see if there"019s something similar on your screen when trying to edit the picture you wish to upload. If so, click on it and that should allow you to edit the picture.
You submitted a pic for the contest under "My Account" and that's the place where we will be uploading profile pics from now on. You can go back in the same place (My Account is still on the upper right) to change it if you'd like. The "profile pics" we were using on the old platform won't be used anymore.
