I am having the same problem with uploading my icon 🙁 What should I do?
You have the same problem as Pawpad; the forum only understand one account per email address. If you had a different account name in the past (on the old forum?) and it got migrated here, it conflicts with any updates you try to do with your current account. If you would like I can easily fix it for you. Please just write me a PM or email letting me know which is the account you prefer to have active, and that I have permission to delete the old, extra account. Note that deletion cannot be undone!
