Why am I getting undefined control sequence when using fncychap Glenn style?

Question

Hi everyone and thank you for reading me,

I am playing around with a phd thesis latex template and I am trying to set the Glenn chapter style from the fncychap package. The problem is that when I try to compile with it the following error comes up:

 ERROR: Undefined control sequence.

--- TeX said ---
\@mkboth ...nguage {\languagename }}\def \bbl@arg 
                                                  {#1}\ifx \bbl@arg \@empty ...l.199 \tableofcontents

                   % Prints the main table of contents

Nonetheless, I should note that this only happens when using the Glenn style, as any other does not produce the error.

A working example may be found in overleaf as this is part of a somehow complicated phd theses template: https://www.overleaf.com/latex/templates/template-for-a-masters-slash-doctoral-thesis/mkzrzktcbzfl#.Wu7w3y-mN26

Just add \usepackage[Glenn]{fncychap} to that template and you get the error.

Any one's got a clue on this one?

I had the same issue as you.

A solution working was to redefined "\tableofcontents" as :

\makeatletter
\renewcommand\tableofcontents{%
  \null\hfill\textbf{\Large\contentsname}\hfill\null\par % line to comment if Glenn style also wanted here
  \@mkboth{\MakeUppercase\contentsname}{\MakeUppercase\contentsname}%
  \@starttoc{toc}%
}
\makeatother

By default, the title "Contents" is center, If you want it to be like others (with Glenn style) : comment the 3rd line

To call the table of contents:

\chapter*{Table of Contents} %if you want in Glenn style also
\tableofcontents
