Avatars sure seem to cause a lot of problems here
I see your membership level is that of Junior Member. This would mean that you are allowed to choose from one of the stock avatars hosted by CAF. In order to be able to upload your own custom avatar, you will need to have the status of Regular Member. Please see this table for more information
You will become a Regular Member when you have belonged to CAF for at least six months AND have made at least 500 posts.
I quickly glanced through CAF's stock avatars, and didn't see any named Ora et Labora, so I assume that refers to a custom avatar. Did you just recently try to upload it? Has it ever displayed here before?
