[Tex/LaTex] LaTeX Warning: Citation ‘aglarov02’ on page 3 undefined on input line 9

bibtexcitingoverleafundefinedwarnings

I'm new to latex and I'm using Overleaf. I encountered a warning during the introduction of my first citation. I failed to find a solution to my problem by reading tutorials and forums, although I found topics about the exact same problem.

Packages I use in my pre.tex file

\usepackage[backend=biber,style=authoryear]{biblatex}
\addbibresource{bibliography.bib}

reference in question in my bibliography.bib file :

@book{aglarov02,    address = {Makhachkala},    edition = {Yupiter},    title = {Andijcy: {Istoriko}-{etnografičeskoe} issledovanie [{Les} {Andi}: {étude} historico-ethnographique]},  shorttitle = {Les {Andis}},     author = {Aglarov, M. A.},  pages = {3},
    date = {2002}

Text in my main file:

les Andis ont été recensés comme Avars entre 1959 en 1989 (\cite[p. 3]{aglarov02}).

Warning content :

LaTeX Warning: Citation 'aglarov02' on page 3 undefined on input line
9.

Thanks in advance for your time and effort,

Neige

I finally solved this problem by replacing

\usepackage[backend=biber,style=authoryear]{biblatex} 
\addbibresource{bibliography.bib}

...by the exact same text !

It works for me after running

I removed the ./ from the bibliography style as it is not installed in the current directory.

I saved the bibliography entry you posted as ref.bib in the current directory, and the code below as file.tex

\documentclass[a4paper,11pt]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage[hidelinks]{hyperref} % Hyperref package for url's and [hidelinks] option to remove collouring

\title{Test}
\author{Thanos}

\begin{document}

\maketitle
\tableofcontents

\begin{abstract}
  This is abstract
\end{abstract}

\section{Section 1}

Referecnce example~\cite{ref:thanos}

\bibliographystyle{IEEEtran}
\bibliography{ref}

\end{document}

[Tex/LaTex] Why I am getting LaTeX Warning: Citation on page undefined on input line

In your first code (class memoir) you have a missing \bibliographystyle{} in your code. The bibliography style defines the layout of your bibliography. Because I do not know which style you need I just used plain.

So the following MWE

\RequirePackage{filecontents}
\begin{filecontents}{\jobname.bib}
@manual{abntex2classe,
  Author = {abnTeX2 and Lauro},
  Organization = {Equipe abnTeX2},
  Title = {A classe abntex2},
  Note = {Substitui \cite{abntex2classe2}},
  Year = {2013}
}
@manual{abntex2classe2,
  Author = {abnTeX2 and Lauro},
  Organization = {Equipe abnTeX2},
  Title = {A classe abntex2},
  Year = {2013}
}
\end{filecontents}


\documentclass[10pt,a5paper,twoside]{memoir}

\begin{document}

\cite{abntex2classe}

\bibliographystyle{plain} % <===========================================
\bibliography{\jobname}

\end{document}

results in

I do not know your second used class abntex2, but it seems that it predefined a special bibliography style to be used. Therefore you need not to add an own bibliography style.
