Duplicates: U4-9857
I installed Umbraco 7.6 to test it out in a sandbox. I installed it with a username of "admin@admin.admin" (because the installer requires an email address for the username). I then did other stuff for a while, so Umbraco logged me out. I then logged back in, and went to the users section to change the username from "admin@admin.admin" to "admin". When I clicked save, I got this error message:

Here are the most recent entries from my Umbraco log file:
