I am trying to create a document with fancyhdr and a pretty long header. It works on all pages except the first page, where the text flows into the header. On the following pages the text starts after the header is finished.
Why doesn't the text get bumped down by the header? What is different about the first page and how can I fix this?
Here is a simple test case showing my problem:
\documentclass{article}
\usepackage{fancyhdr}
\pagestyle{fancy}
\usepackage[german]{babel}
\usepackage[utf8]{inputenc}
\fancyhf{}
\chead{
I am a header \\
with multiple lines \\
many lines \\
many many lines \\
many many many lines
}
\usepackage{blindtext}
\begin{document}
\section{A section}
\blindtext[30]
\end{document}
