I can actually see your photo when I go to your profile page, hence it has been uploaded successfully. Can you confirm if you see the same thing on your end? If not, can you log out then log back in.
Previously when it failed, I had everything else already filled out. Apparently it didn’t like that.
Please try to resize the image to 250x250dpi and crop it to include only your head and shoulders.
If it meets those requirements and you still can't upload it then please try clearing your cache and cookies and using a different browser to check if the problem persists.
Please try clearing your cache and cookies or logging in with another browser to upload your image. If you`re receiving any errors on your end let me know, thank you.
