The site you pointed us to in the CB has the credentials realm "Automated Splice Site Analyses". I don't see that anywhere in your code. Instead, your realm is simply "Title": 
$mech->credentials(   'www.edited.com:443', 'Title', $username, $passw
+ord );

Change the second parameter to "Automated Splice Site Analyses" and you might have more luck.

FYI here's the relevant code in LWP::UserAgent: 

sub credentials
{
    my $self = shift;
    my $netloc = lc(shift);
    my $realm = shift || "";
    my $old = $self->{basic_authentication}{$netloc}{$realm};
    if (@_) {
        $self->{basic_authentication}{$netloc}{$realm} = [@_];
    }
    return unless $old;
    return @$old if wantarray;
    return join(":", @$old);
}

As you can see, if $realm has the wrong value, one that isn't in the HoHoA, nothing will be returned.

update WWW::Mechanize overrides this method and allows a 2 argument form: just username and password. That way you can avoid this mess with the realm altogether. Thanks for the tip, erix, although maybe unintentional... :) 

$mech->credentials( $username, $password );
