Fatal Error when creating a guest author with a name of a user that already exists. #1135
Description
We ran into an issue while trying to create a Guest Author with the display name Joe Greene. When clicking “Create Guest Author,” the site immediately returned a 500 Internal Server Error.
No errors were logged in debug.log, and no fatal error notification was sent to the site administrator, which was unexpected. The only clue came after checking the wp_users table, where I discovered that an existing subscriber already has the display name and slug Joe Greene.
Unfortunately, since nothing was logged, I don’t have a stack trace or specific error message to share. The only output shown was the generic Internal Server Error page.
Just figured I would report it.
