I am using joomla1.5 and CB1.2.

On registration form there are two fields 'email' and 'password' which shows no error at client side. But when form is submitted it shows popup javascript message with blank page in background. The errors are:-
Email : This is not a valid email address.
Password : Password and verification do not match, please try again.

After clicking OK button, registration form displayed again with same error on top and all other text fields shows word 'notapplicable'

Please help me.
