I'm new to latex. It has been now almost one month trying to learn for my thesis. If I had a problem I would just type it here, and finally get the solution. But with this command autocite it is always problematic. It is now been 4 days trying to figure it out. Well I switched from natbib to biblatex and even biber. Everything works fine and I had my bibliography and I used the style verbose. But when I try to use the command autocite it doesn't show them.
On the other hand, I worked with footcite it gives me the citation in footnotes, which I do not understand. But I don't know why this command do not work in my .tex file even though I switch to biblatex and biber.
An example of what i did
\documentclass[12pt,a4paper]{book}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[french]{babel}
\frenchbsetup{FrenchFootnotes=false}%more common footnote style
\usepackage{fnpct}%just a cool package for nice footnotes
\usepackage{csquotes}
\usepackage[hang,flushmargin]{footmisc}
\usepackage[pdftex]{graphics}
\usepackage{enumerate}
\usepackage{{\images}}
\usepackage{blindtext}
\usepackage{tikz}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{xcolor}
\usepackage{epigraph}
\usepackage[nottoc]{tocbibind} %to disply bibliography in the table contents
\usepackage[backend=biber,style=verbose-trad2,natbib=true,sorting=nyt]{biblatex}
\addbibresource{mabib.bib}
\begin{document}
