I have just launched a client site and they have had a LOT of users sign up and I've had an issue where 1 user uploaded an avatar image. Then the second user signed up a day after and uploaded an avatar image.
Now both have the same avatar image with the older sign up being over written by the newer one. I thought that maybe it was a file name collision however the database entry for user_avatar for the older sign up has actually changed to the path of the new users avatar image.
Do you have any idea how I could go about debugging this?
