MWE using svmult class from https://resource-cms.springernature.com/springer-cms/rest/v1/content/20568/data/v8

\documentclass[graybox]{svmult}
\usepackage[british]{babel}

\begin{document}


\section{Introduction}
\label{introduction}


Foo Bar


\bibliographystyle{spbasic}
\end{document}

When compiled via pdflatexmk gives me the following error:

./authorsample.aux:5: LaTeX Error: Missing \begin{document}.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...


l.5 \newlabel{introduction}{{1}{1}}[
                                    None]

authorsample.aux is

\relax 
\bibstyle{spbasic}
\immediate\closeout\minitoc
\@writefile{toc}{\contentsline {section}{\numberline {1}Introduction}{1}\protected@file@percent }
\newlabel{introduction}{{1}{1}}[None]

How can I use svmult with babel?

    the class loads ntheorem with thref option, and this only works if it is loaded after babel (see the ntheorem docu). So ask the class maintainer what to do. – Ulrike Fischer Aug 20 '20 at 22:10
  • Thank you. Do you have any advice on identifying the class maintainer? – mritz_p Aug 21 '20 at 07:25
  • well you downloaded a large zip. So look in the various files, or check their website. Btw: the class redefines nearly all latex structures including a number of internal commands. So you should use it only if it really fits, it would be difficult to adapt or correct. – Ulrike Fischer Aug 21 '20 at 07:48
  • I have grep'ed all files in that ZIP for e-mail addresses. The only ones in there are meier@tu.edu, name@email.addres and smith@smith.edu. All examples. I did download an older version from https://www.springer.com/birkhauser/mathematics?SGWID=0-40292-2-122598-0 and found texhelp@springer.de. I'll reach out now. Wish me luck :D – mritz_p Aug 21 '20 at 18:34

    well if everything fails you can always edit the class. But if someone asked you to use it, they should imho also offer support for it. – Ulrike Fischer Aug 21 '20 at 18:38
  • Agreed. Hoping for the best. Thanks @UlrikeFischer – mritz_p Aug 21 '20 at 18:42

The only way I could find is to edit the class by removing the ntheorem package I do not require, as suggested in comments.

diff --git a/svmult.cls b/svmult.cls
index 2c39e97..62287b8 100644
--- a/svmult.cls
