I made a very big stupidity on my site and do not know how to solve.
I removed the user "admin" by user "admin" from group "Admins" to replace by another user (a user with another name, but that is mine).
My site has a limit of 13 years old. But when I try to confirm my age, the site redirects to the login screen (the site is closed). I enter again and he returns to the old confirmation screen.
How can I solve this? I need this site to 01/01/2015
