# Change pagestyle to plain for first page of an unnumbered chapter

I'm writing my undergrad senior-thesis (at a German university) with the following specifications:

\documentclass[12pt,headsepline,footsepline]{scrreprt}
\usepackage{fancyhdr}
\pagestyle{fancy}
\renewcommand{\chaptermark}[1]{ \markboth{#1}{} }
\renewcommand{\sectionmark}[1]{ \markright{#1}{} }
\usepackage{apacite}
...
\begin{document}
\begin{titlepage}...\end{titlepage}
\pagenumbering{roman}
\tableofcontents
\listoffigures
\listoftables
\chapter*{List of Abbreviations}
...
\chapter*{Abstract}

\chapter{Introduction}
\setcounter{page}{1}
\pagenumbering{arabic}
...
...
\bibliographystyle{apacite}
\bibliography{references}



It's better to use the scrbook class, rather than resorting to low level tricks like \pagenumbering.

\documentclass[12pt,headsepline,footsepline,oneside]{scrbook}

\usepackage{fancyhdr}
\pagestyle{fancy}
\renewcommand{\chaptermark}[1]{\markboth{#1}{}}
\renewcommand{\sectionmark}[1]{\markright{#1}}

\usepackage[nosectionbib]{apacite} % the bibliography is a chapter

\begin{document}
\begin{titlepage}...\end{titlepage}

\frontmatter
\tableofcontents
\listoffigures
\listoftables
\chapter{List of Abbreviations}

\chapter{Abstract}

\mainmatter
\chapter{Introduction}

\nocite{*} % to populate the bibliography

\bibliographystyle{apacite}
\bibliography{references}

\end{document}


In my experiment, no word in the header is capitalized.

You probably have to better customize the parameters for fancyhdr.

For the references title you should try the following command

\renewcommand{bibname}{References}


(or whatever you want instead of "References") after the command

\usepackage{apacite}


\markboth{List of Abbreviations}{}

after the \chapter* command and it should work.
