Why can't I change my profile picture anymore?
I went to setting and tried to change it but it did not let me.
Perhaps the picture you wanted to change it to was too large. Maximum picture size is 1MB.
Hover over your username and click settings. Scroll down and click browse. Choose you picture. The maximum size is 1 MB. Make sure you click save changes (scroll back up).
Something must be wrong. Try contacting a moderator or staff, I'm sure they can help you.
you must make sure the photo is small enough. you may have to crop your photo.
