I was trying to login to an old Wordpress site I had forgotten the password too, had too many attempts at the password and got myself temporarily locked out.
I have since reset the password, (directly in the MySQL database), but still can't login because of my "temporarily lock out".
Wordpress keeps telling me to "please try back in a short while" ... it has been 3 hours already!
I have googled this extensively, and no one seems to know how long that "short while" is...
