As discussed in Mumble on July 30th, this is a known limitation that we currently cannot fix. However, we can improve the routine by checking if the POST data exists:

if (null !== ($dns = $input->post('dns')) {
    $currentDomain = $dns; 
}

if (null !== ($urlPrefix = $input->post('urlPrefix')) {
    $currentPrefix = $urlPrefix; 
}

if (null !== ($urlSuffix = $input->post('urlSuffix')) {
    $currentSuffix = $urlSuffix; 
}
