I am using classicthesis in a document that also needs to use Persian text (in Arabic script). I am using polyglossia and XeLaTeX with this. I want the main font to be Palatino/TeX Gyre Pagella. Unfortunately, I am stuck with headings that are Palatino, but not in small caps. I have no idea what I am doing wrong. For some headings, the first letter is compiled in small caps, but the remainder isn't.
Here is my MWE:
\documentclass[

\begin{document}
\frenchspacing
\raggedbottom
\tableofcontents
\cleardoublepage
\chapter{Testkapitel}
\section{Testabschnitt}
\end{document}
I came along and adopted this, but I did not get me anywhere, unfortunately.
Addition (Feb 20): I just realized that there is also some relevant error messages. I don't know what they're telling me though:
In verse.sty:
34: Command \theHpoemline already defined. ...}{\arabic{verse@envctr}.\arabic{poemline}}
In the MWE above:
104: Undefined control sequence. \begin{document}
104: Missing font identifier. \begin{document}
104: Missing number, treated as zero. \begin{document}
