The error forbade the user to save:

Question

I have a problem that I cannot solve

3 errors did not allow this user to be saved:

• Email address cannot be empty
• Password confirmation does not match password
• Password is too short (minimum 8 characters)

I can’t understand how to get rid of. 3 error prohibited this user from being saved: All I want to display is errors in bullets. Any ideas on how to go along with this? By the way, I am using Devise.
