I’ve had this issue come up twice now and I am stumped.
I have created a client login for ExpressionEngine and the client has been been making changes. Over this weekend the client tried to login and was denied and she tried 4 times. She then waited a hour and tried again and no luck. She then waited a full day and still no luck. She then tried to reset the password and no luck.
She has called me and I have tried to reset the password and no luck. I have even tried deleting her account, making a new account with the same user name and new password, but still no luck. However if I delete the account and make a new account with a new username and password then it works.
I have also had this happen to one of my superadmin accounts before.
Anyone have any idea whats going on and how to fix this?
