Error Password

Hi, First of all thank them for the great forum they have created for the community. I installed it very recently and I have a problem when the users register. When they are in the registration area, they enter the username they want and their email and a red warning appears to enter their password. What is failing? I do not give the problem.

Thanks in advance.
