Missing header in Acknowledgement part

Question

I have set up the acknowledgement part as follows:

\section*{Acknowledgements}
Thanks Mum.

But then, the header is missing, except the line at the top is appeared. As I want to make it standardized with the rest of the part of my document, I need to, by any means, include the header. When I search in the latex code or setting, there is no such like \usepackage{fancyhdr} is used. I used a template found somewhere actually, and my question is how to add such a header.

EDIT:

I found, perhaps, the part that configures the header. Nevertheless, I don't know how to customize it in order for it to affect on the newly added acknowledgement part as well. The part is as below(options.tex):

\usepackage[automark]{scrpage2}
\usepackage{ifthen}

\pagestyle{scrheadings}
%\automark[chapter]{section}
\clearscrheadfoot
\ohead{\pagemark}
\ihead{\headmark}

\renewcommand*{\chapterpagestyle}{scrheadings}

\clubpenalty = 10000
\widowpenalty = 10000
\displaywidowpenalty = 10000

In main latex code:

\documentclass[%
12pt,
oneside,
halfparskip+,           
headsepline,            
titlepage,

pointlessnumbers,   
bibtotoc
]
{scrreprt}

\usepackage[T1]{fontenc}
\usepackage{pseudocode}
\usepackage[utf8]{inputenc}
\usepackage{abstract}
\input{options.tex}

\setlength{\headheight}{1.5\baselineskip}

Answer 1

You're typesetting the "Acknowledgements" as an unnumbered \section, although scrreprts highest-level sectioning command is \chapter. Also, scrreprt by default uses oneside, and \addsec (KOMA-Scripts alternative to \section*), doesn't update the header in oneside mode (although \addchap, the alternative to \chapter*, would). Solution: Manually update the header by using \markright{Acknowledgements}.

\documentclass{scrreprt}

\usepackage[automark]{scrpage2}
\pagestyle{scrheadings}
\clearscrheadfoot
\ohead{\pagemark}
\ihead{\headmark}
\renewcommand*{\chapterpagestyle}{scrheadings}

\usepackage{lipsum}

\begin{document}

\addsec{Acknowledgements}
\markright{Acknowledgements}

\lipsum[1]

\end{document}
