Django change password issue, super(type, obj): obj must be an instance or subtype of type

i'm having some trouble with my changepassword form, it continues to give me the same error: super(type, obj): obj must be an instance or subtype of type this is my form: ``` class PasswordChangeForm(forms.Form): current_password = forms.CharField(label=u'Current Password', widget=forms.PasswordInput(render_value=False)) new_password = forms.CharField(label=u'New Password', widget=forms.PasswordInput(render_value=False)) retyped_password = forms.CharField(label=u'Retype New Password', widget=forms.PasswordInput(render_value=False)) def __init__(self, data=None, user=None, *args, **kwargs): self.user = user super(UserProfileEditForm, self).__init__(data=data, *args, **kwargs) def clean_current_password(self): cleaned_data = self.cleaned_data current_password = cleaned_data.get('current_password', '') if not self.user.check_password(current_password): raise ValidationError('Wrong current password.') return current_password def clean(self): cleaned_data = self.cleaned_data new_password = cleaned_data.get('new_password', '') retyped_password = cleaned_data.get('retyped_password', '') if len(new_password) == 0 or len(retyped_password) == 0: raise ValidationError('Blank password fields.') if new_password != retyped_password: raise ValidationError('New password and retyped password do not match.') return cleaned_data def save(self): self.user.set_password(new_password) return self.user ``` any ideas?
