Custom self registration page not working

Question

I am using a self registration page for guest user sign up.It is showing this error Your request cannot be processed at this time. The site administrator has been alerted.As far as i think it is because of create portal user as it is not returning userid

global class SelfRegisterController {    

@TestVisible 
private static boolean isValidPassword(String password, String confirmPassword) {
    return password == confirmPassword;
}

@TestVisible 
private static boolean siteAsContainerEnabled(String communityUrl) {
    Auth.AuthConfiguration authConfig = new Auth.AuthConfiguration(communityUrl,'');
    return authConfig.isCommunityUsingSiteAsContainer();
}

@TestVisible 
private static void validatePassword(User u, String password, String confirmPassword) {
    if(!Test.isRunningTest()) {
        Site.validatePassword(u, password, confirmPassword);
    }
    return;
}

Any help would be very helpful.

Answer 1

Check your email (or ask the sys admin to do so if you are not the admin). It will have the actual error message in it.

I think you are missing the ProfileId. When you create a user, you should define a ProfileId for an user by running a code

u.ProfileId = [ SELECT Id FROM Profile WHERE Name = 'Partner Community User'];

Replace Partner Community User with the name of desired profile
