# Problem : No section/subsection label appears in the titles [duplicate]

Here is my problem : in the titles of my sections and subsections, labels don't appear, leaving titles with only text (no numbers as "1.1.", etc.). A important remark is that this problem does not occur when building my document on another computer (at work)... I have no other problems with my document, and every other labeling (cross references for instance) works perfectly fine.

I use the texlive package. Here is a MWE, showing all the packages I use for my document, and the corresponding output :

\documentclass[a4paper,11pt,oneside,fleqn,openany]{book}

Any ideas ?

• Make an update of package titlesec. – Johannes_B Aug 27 '16 at 16:22

• Please tell us which version of the titlesec package you use. – Mico Aug 27 '16 at 17:16

Following the link of touhami in his/her comment on my above post, I tried the solution of egreg, which consists in the following five lines to add just after the \usepackage{titlesec} :
\usepackage{etoolbox}
