\footcites leads to an error

[LukasCBossert]

Consider this MWE

\documentclass{article}
\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@Book{test1,
  author = {A. Author},
  date = {2018}
}
@Book{test2,
  author = {B. Buthor},
  date = {2017}
}
@Book{test3,
  author = {C. Cuthor},
  date = {2017}
}
\end{filecontents*}
\usepackage[%
 backend=biber,
 bibstyle=ext-authortitle,
 citestyle=ext-authoryear,
]{biblatex}
\addbibresource{\jobname.bib}
\begin{document}

\footnote{\cites%
[1--3]{test1}%
[4--6]{test2}%
[7--10]{test3}}

% Does not work
\footcites%
[1--3]{test1}%
[4--6]{test2}%
[7--10]{test3}

\end{document}

It seems like \footcites is not working !?

Thank you very much for that bug report. This was a small copy-and-paste error. It has been fixed in e1ab5d4.

An updated version (v0.5a) is on its way to CTAN and should arrive in TeX distributions in the next few days. In the meantime

\DeclareMultiCiteCommand{\footcites}[\mkextblxfootcite]
  {\footcite}{\multicitedelim}
\DeclareMultiCiteCommand{\footcitetexts}[\mkextblxfootcitetext]
  {\footcitetext}{\multicitedelim}

should be a work-around if you use (cite)sytle=ext-authoryear.

Thank you very much for the very quick debug! It works very well! So I will close this issue...
