[Tex/LaTex] Abstract not on a separate page

abstractkoma-scriptpage-breakingtitles

I'm writing a scientific paper for my university. The page after my table of contents I would like to start my document with a abstract, directly following with the first section. As far as I know, the document class scrartcl will not insert page breaks after the abstract. Somehow my abstract is on an own page.
Here's my code:

\documentclass[a4paper,
    12pt,
    titlepage,
    twoside, 
    abstracton,
    ]{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[ngerman]{babel}
\usepackage{amsthm}

\usepackage{natbib}
\usepackage{url}

\usepackage{booktabs} 
\usepackage{multirow}  
\usepackage{graphicx} 
\usepackage{wrapfig} 
\newtheorem{bsp}{Beispiel}

\graphicspath{{Grafiken/}} 
\usepackage{everyshi}
\usepackage[absolute]{textpos}
\setlength{\TPHorizModule}{1mm} 
\setlength{\TPVertModule}{1mm}

\begin{document}

\begin{textblock}{150}(32,155)
\setlength{\parindent}{0cm}
\begin{Huge}
\textbf{\textsf{blabla} }
\end{Huge}
\vspace{1cm}

\hspace{1.25cm}\Large{\textsf{...}}
\hspace{1.25cm}\Large{\textsf{bla}}
\vspace{1cm}
\hspace{1.25cm}\Large{\textsf{bla}}

%Autor
\hspace{1.25cm}\Large{\textsf{...}}

\vspace{3.5cm}
\hspace{1.25cm}\Large{\textsf{\today}}
\end{textblock}

\end{titlepage}
\null\newpage

\linespread{1.25} 
\setlength{\parindent}{0cm}{right}{top}{bottom}{headheight}{headsep}{footheight}{footskip}
\pagestyle{headings}
\setcounter{secnumdepth}{3}

\tableofcontents % Inhaltsverzeichnis
\newpage

\begin{abstract}
Abstract\dots blablablablablablablablablablablablablabla blablablablabla    blablabl ablablablablabla blablablabla blablablablablablablablablablablablablablabla
\end{abstract}
\section{Einleitung}
(...)
\end{document}

What's the cause?

Best Answer

With the titlepage class option, a page break will also be added after the abstract environment (like it would when using the article standard class). Solution: Either don't use this option at all, or disable it before the abstract using \KOMAoptions{titlepage=false}.

\documentclass[titlepage]{scrartcl}

\usepackage{lipsum}

\begin{document}

\author{(Author}
\title{(Title)}

\maketitle

\KOMAoptions{titlepage=false}

\begin{abstract}
\lipsum*[1]
\end{abstract}

\section{foo}

\lipsum*[1]

\end{document}
