Maketitle error

Why do I constantly get this error:
There’s no line here to end. maketitle

When I learned to use latex I was told to use maketitle where I want to have my title placed. What is written in the title is defined by title. Like this:

documentclass[a4paper,oneside,abstracton]{scrartcl}

usepackage[utf8]{inputenc}
%usepackage[latin1]{inputenc}               %Zeichencodierung Text
usepackage[T1]{fontenc}                     %Schriftsatz Dokument

%%Language settings
usepackage[english]{babel}                  %ngerman for German
usepackage{csquotes}                        %[babel,quotes=english]
usepackage{caption}
addtocaptionsenglish{renewcommand{contentsname}{Table of Contents}}
%renewcommand{contentsname}{Table of Contents}   % only works when not using babel

%%Paper adjustments
usepackage{graphicx}
usepackage{epstopdf}                        %if problems with importing .eps graphics
%usepackage{a4wide}                         %obsolete and replaced by geometry
usepackage[a4paper,bottom=3.1cm]{geometry}  %also with command geometry{options}
usepackage{changepage}
usepackage{titling}
