[Tex/LaTex] Maketitle error

errorstitles

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}
\addto\captionsenglish{\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}


\begin{document}

\title{\LARGE Advanced Course \\ [1em] \huge \textbf{Tools}}
\author{Muster1 \hspace{1cm} Muster2}
\date{\\[1em] {Today} \\ [0.8cm] Supervisor Dr. Muster3 \\ [0.5cm] Institut \\ University of Whatsoever}

\clearpage
\maketitle
\thispagestyle{empty}
\renewcommand\abstractname{Abstract}
\renewcommand\tablename{Table}
\newpage

\end{document}

Best Answer

The problem is that you are using \\ (inside \date) when TeX is in vertical mode. TeX has the vertical and the horizontal modes. Horizontal mode is for putting letters into lines and assembling those into paragraphs, vertical mode is for putting those paragraphs and other things onto the page. \\ is a horizontal mode command that breaks the current line inside a paragraph. The error you are getting, no line to end, is exactly right: you have not begun a line, i.e. entered horizontal mode, yet.

Use \vspace{1em} instead of \\[1em] as vspace is a vertical mode macro that will function exactly how you want it to.
