# Random Page after Chapter/Before Mainmatter

I get a weird blank page in front of my mainmatter. I tried for hours to get it removed in different ways, but I do not seem to find my mistake.

My .tex:

\documentclass[a4paper, oneside, 12pt]{scrbook}

\usepackage{blindtext}

\begin{document}

\frontmatter

\chapter{Abbrevation}
\blindtext

\mainmatter

%%%% Put chapters here
/\chapter{Chapter}
\blindtext

\end{document}


EDIT: As you can easily see, my problem is created by a Typo in front of \chapter. The / is easily missed.

The weird result I do not want:

• Welcome to TeX.SE. It is generally helpful to trim out the excess so that you end up with a minimal working example. In this case, however, I assume the blank page is because oneside tells TeX that the main matter should always begin on an odd numbered page. Try twoside instead. – Teepeemm Sep 26 at 1:18
• @Teepeemm IIRC it is the other way round. Such blank pages are expected with twoside but not with oneside. Therefore, a minimal working example is crucial here. – Ralf Stubner Sep 26 at 10:20
• Thanks for the Responses. I tried recreating my error with a minimal approach, somehow, i wasnt really abled to. I tried to track down the reason for this by removing package by package. This led to an unrelated error message which did let me find the reason for my mishap: I had an / in front of the \Chapter following \mainmatter. I will edit the question anyways to a more simple version. – Timo John Sep 26 at 21:12
