Thread:Project:Support desk/Upgrade from MW 1.18.1 to 1.23.5 broke sysop and Bureaucrat users functionality/reply (7)

I believe MediaWiki 1.23.5 forces all my logins:

USERNAME

USername

username

To:

Username

All 4 succeed logging into my Edir account: USername.

Forces Username displayed to: Username,

Browser saves same password to 4 usernames:

USERNAME

USername

username

Username

Still can't Merge accounts: USername to Username.

Only way to fix is delete all USernames from database and leave orphaned records!
