- removed added debug messages (maybe they will come back in accordance to code-style guidelines?) - converted $a->get_baseurl() back to App::get_baseurl() - reverted back other code I have touched/merged as this was double: (substr($url, 0, 4) !== 'http') on $url = 'https://bla'; will be FALSE (means found http at start), too.
