How to make page numbers to plain numbers in scrlttr2?

Question

I wrote a letter with multiple pages in scrlttr2. Now I get the page numbers "Seite 2" and so on, but I simply want "2" there.

I don't find an option how to turn this off, neither in the scrguide.pdf nor in the source code. This reproduces the error (I use lyx, but that doesn't matter):

\documentclass[ngerman,fromrule=off,addrfield=on,backaddress=off,fromalign=left,enlargefirstpage=off]{scrlttr2}
\usepackage[latin9]{inputenc}
\usepackage[a4paper]{geometry}
\usepackage{blindtext}
\geometry{verbose}
\pagestyle{plain}

\makeatletter
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Textclass specific LaTeX commands.
\newif\ifletterclosed
\AtEndDocument{\ifletterclosed\else\end{letter}\fi}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% User specified LaTeX commands.

\pagenumbering{roman}

\makeatother

\usepackage{babel}
\begin{document}

\setkomavar{fromaddress}{from me}

\begin{letter}{to adress}

\setkomavar{date}{today}

\setkomavar{subject}{spam}

\begin{letter}{}
\LoadLetterOption{DIN}
\makeatletter
%\@setplength{refvpos}{4cm}
%\@setplength{subjectaftervskip}{1cm}
\makeatother


\opening{Dear stranger,}

\Blindtext 

\closing{Bye}

\setkomavar{signature}{My name}

\end{letter}
\end{document}

Commenting \LoadLetterOption{DIN} doesn't help. I don't see any further options that might be related to page numberings.

Answer 1

You have to redefine the \pagemark command:

\renewcommand\pagemark{\usekomafont{pagenumber}\thepage}

Additional remarks:

The letter-class-option file DIN is loaded by scrlttr2 automatically.

I do not understand why you are nesting letter environments and why you are closing the outer letter environment using \AtEndDocument. So in the following MWE there is only one letter environment:

\documentclass[ngerman,backaddress=off,fromalign=left]{scrlttr2}
\usepackage[latin9]{inputenc}
\usepackage[a4paper,verbose]{geometry}
\usepackage{babel}


\pagenumbering{roman}
\renewcommand\pagemark{\usekomafont{pagenumber}\thepage}


\usepackage{blindtext}% dummy text
\begin{document}

\setkomavar{fromaddress}{from me}
\setkomavar{signature}{My name}
\setkomavar{date}{today}
\setkomavar{subject}{spam}

\begin{letter}{to adress}

  \opening{Dear stranger,}
  \Blindtext 
  \closing{Bye}
\end{letter}
\end{document}
