After updating a character, any url I use for the avatar pic has all the slashes after the http:// converted to %2F.
This happened when I changed the number of visible transactions and didn't touch the url. I had one there fine for about a month previously, never touched my Edit Char page since until today.
I've tried a few different pictures in different directory levels and kept getting the same result. I left a sample of what happens as my current avatar.
Keep up the good work. :)
