I am using UmbracoCMS 7.6.2 in one of my site.
Today when I tried to login in Umbraco backoffice using mysite/umbraco, will my working credential, it shows me error:
You probably tried to login with the wrong password too many times and umbraco locked you out.
To fix this go to the database, open umbracoUser table and update userNoConsole to 0 for your username.
umbracoUser
userNoConsole
