LoF, LoT, Abstract, Acronyms non-numbered in ToC - why?

Question

The solution of LOF+LOT+BIB in TOC with numbered chapter does not work in my case.

Admittedly I used a template of some other person - when I produce a Pdf with his code all above mentioned sections are numbered. However, when I produce the Pdf of my code, these sections remain unnumbered - which is undesired. Can anybody help me on, please? I suspect to depends on some counterproductive usepackage

Here is the code:

\documentclass[10pt,a4paper,bibliography=totocnumbered,listof=totocnumbered]{scrartcl}
\usepackage[tocbibind]
\usepackage[utf8]{inputenc}
\usepackage{fancyhdr}
\usepackage{titlesec}
\usepackage[subfigure,titles]{tocloft}
\usepackage{caption}

\setcounter{tocdepth}{2}
\renewcommand\cftchapafterpnum{\vskip8pt}
\renewcommand\cftsecafterpnum{\vskip10pt}

\usepackage{listings}
\lstset{basicstyle=\footnotesize, captionpos=b, breaklines=true, showstringspaces=false, tabsize=2, frame=lines, numbers=left, numberstyle=\tiny, xleftmargin=3em, framexleftmargin=3.0em}
\makeatletter
\def\l@lstlisting#1#2{\@dottedtocline{1}{0em}{1em}{\hspace{2,0em} Lst. #1}{#2}}
\makeatother

\geometry{a4paper, top=28mm, left=31mm, right=28mm, bottom=26mm, headsep=4mm, footskip=4mm}

\begin{document}

\titlespacing{\section}{0pt}{12pt plus 4pt minus 2pt}{2pt plus 2pt minus 2pt}
\renewcommand{\contentsname}{II Contents}
\phantomsection

\addtocounter{section}{1}
\tableofcontents
\pagebreak
\listoffigures
\pagebreak
\listoftables
\pagebreak


\noindent\section{List of Acronyms}
\begin{acronym} 
\setlength{\itemsep}{-\parsep} 
\acro{CEO}{Chief Executive Officer}     
\end{acronym}
\newpage


\setcounter{section}{0}
\renewcommand\refname{0. Introduction}
\section{{\Large Introduction}}
\markright{Introduction}
\phantomsection
\addcontentsline{toc}{section}{0. Introduction}
\addtocontents{toc}{\vspace{-0.5em}}

Lorem ipsum...

\newpage
\setcounter{section}{1}
\renewcommand\refname{Chapter 1}
\section*{{\Large Chapter 1}}
\markright{Chapter 1}
\phantomsection
\addcontentsline{toc}{section}{Chapter 1}
\addtocontents{toc}{\vspace{-0.5em}}

Lorem Ipsum again

\end{document}

Answer 1

The packages tocbibind, tocloft, titlesec and fancyhdr are not recommended with a KOMA class. They offer capabilities that the standard classes miss. KOMA-script provides the capabilities, but they are overrun by the aforementioned packages. Not using them is the solution.

It was stated, that the above code was found in a template. The code does so many many strange things, that i can't advice anybody to use it.
Be careful, many templates are bad.
