i'm in trouble.
Today I deleted 2 plugins of my Joomla 3.x and after that when I tried again to login in my administrator i could not. 

The error is: JAuthentication: :__construct

The solution for the previous versions was to go in the DB and in the table jos_plugins set "name - Authentication - Joomla - published" to 1 from 0.

The problem is, in joomla 3.x we don't have this table. 
What to do now to solve this problem?

Thank you,
I need this fast as I can or my boss will kill me.
