I have some troubles with citations and biber. I'm citing a paper several times and point to different sections in that paper. But sometimes the citation is not shown in the pdf. I can't comprehend when they are not shown. In one section they are shown properly, and in the other section simply a space appears.
First I use
\cite{Shani2011}
and the second time I use the same (copy and paste)
\cite{Shani2011}
Inside the Bib reference, the paper is also shown properly. I got no errors in my console, just a few Overfull \hbox...
and !h float specifier changed to !ht
warnings, and one No backend specified, using Biber backend
. I don't know why this biber warning occurs, my command to compile in texmaker is (% references the current document name):
"/usr/texbin/pdflatex" -synctex=1 -interaction=nonstopmode %.tex|
"/usr/texbin/biber" %|
"/usr/texbin/pdflatex" -synctex=1 -interaction=nonstopmode %.tex|
"/usr/texbin/pdflatex" -synctex=1 -interaction=nonstopmode %.tex|
open %.pdf
Does anyone know where I can start to debug this?
==========================================
EDIT
Ok, here is a minimum example:
\documentclass[12pt,a4paper]{article}
\usepackage[english,ngerman]{babel}
\usepackage[authordate]{biblatex-chicago}
\bibliography{Bibliography2}
\begin{document}
\cite{Shani2011} blabla. \cite{Shani2011} blabla
\end{document}
This produces
Shani und Gunawardana 2011 blabla. blabla
The second citation doesn't gets printed into the pdf. But I found out, if I cite between the two Shani2011 another paper, it works. This
\begin{document}
\cite{Shani2011} blabla. \cite{Shani2009} blabla \cite{Shani2011} blabla
\end{document}
produces this
Shani und Gunawardana 2011 blabla. Shani 2009 blabla Shani und Gun- awardana 2011 blabla
So I don't know why this doesn't work. Any ideas?
EDIT
Here is the Bibliography2.bib:
@article{Shani2011,
author = {Shani, Guy and Gunawardana, Asela},
title = {{Evaluating recommendation systems}},
year = {2011}
}
@article{Shani2009,
author = {Shani},
title = {{Evaluating recommendation systems}},
year = {2011}
}

backend=
argument when loading biblatex. It's there since version 2.0 because before that, bibtex was the default backend. You can ignore it or just addbackend=biber
as an option when you load biblatex.
