I'm struggling with biblatex to have footnote when the \footcite command is issued inside a \begin{center} \end{center} block.

The bibliography works fine, I have the reference number in the text but I'm unable to get the footnote at the same time.

I tried the command:

\footcite{ref1}
\footfullcite{ref1}
\footfullcitetext{ref1}

But it's not wokring.

This is what I have:

\usepackage[
    backend=bibtex,
    style=numeric,
    citestyle=verbose,
    maxcitenames=50,
    maxbibnames=50,
    firstinits=false,
    sorting=none]{biblatex}
\bibliography{biblio} 


\begin{center}
\includegraphics[scale=0.30]{01_Content_Certif_X509}
\captionof{figure}{\emph{Génération et contenu d’un certificat X.509.}\footcite{dumas2013theorie}}
\end{center}

If I used the \footcite command outside the \begin{center} \end{center} block, it works fine.

Can someone help me please?

  • Please consider posting a fully compilable example document instead of several disconnected code snippets (tex.meta.stackexchange.com/q/228/35864). Without a proper MWE to test this my working assumption is that this is not due to the center environment, but rather due to the fact that footnotes don't work in captions.

@moewe, based on your link, this was the solution

\begin{center}
\includegraphics[scale=0.30]{01_Content_Certif_X509}\label{fig:1}
\captionof{figure}{\emph{Génération et contenu d’un certificat X.509.}{\protect\footnotemark}}
\end{center}
\footnotetext{\footcite{dumas2013theorie}
  • In this case it would be possible to reduce the \footnotetext{\footcite{dumas2013theorie}} to \footcitetext{dumas2013theorie}. – moewe Dec 8 '19 at 13:47
