I'm getting
! Missing $ inserted.<inserted text>$ ...y[prenote=myprenote,title={Bibliography}]
The respective line is
\printbibliography[prenote=myprenote,title={Bibliography}]
Is there something off in that line or must the fault lie with the bibliography itself?
The bib contains underscores in URLs, which according to some search results here may cause problems. But does that also count for bibliographies?
\documentclass{...}
and ending with\end{document}
