Footbib package error

Question

I am trying to cite the reference in the footnotes of my document using the footbib package.

I receive the following error:

footbib.sty:92: Package footbib Error: the output routine of LaTeX changed

I am using few packages in order to reduce the problem with the footbib package.

\documentclass[12pt, a4, oneside]{book}

%\usepackage{framed}
%\usepackage{alltt}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

%\usepackage{biblatex}
\usepackage[authoryear]{natbib}
%\bibliographystyle{unsrtnat}

\usepackage{lipsum}
\usepackage[oneside, citeonce(chapter)]{footbib}
\usepackage{csquotes}

 @article{Panebianco-2011a,
    Author = {M. PANEBIANCO},
    Date-Added = {2016-12-26 18:20:51 +0000},
    Date-Modified = {2016-12-26 21:32:38 +0000},
    Pages = {p. 336},
    Title = {Diritto Internazionale Pubblico},
    Volume = {III ed., Editoriale Scientifica, Napoli},
    Year = {2011}}

\begin{document}

\chapter*{Introduction}

\lipsum[1]\footcite{Panebianco-2011a}

\end{document}

The reference used is

@article{Panebianco-2011a,
    Author = {M. PANEBIANCO},
    Date-Added = {2016-12-26 18:20:51 +0000},
    Date-Modified = {2016-12-26 21:32:38 +0000},
    Pages = {p. 336},
    Title = {Diritto Internazionale Pubblico},
    Volume = {III ed., Editoriale Scientifica, Napoli},
    Year = {2011}}

I have tried to use the biblatex package but the errors even increase.

A workaround is to use the biblatex package with the option style equal style=authortitle citing using the command \autocite. But this option is less efficient with respect to the use of footbib package.

Last point, I'd like to change the counter from square brackets [1] to normal parenthesis (1).
