First page of bibliography doesn't display page number

Question

I need to do my thesis and I have used a template of my university in Overleaf. But I have one problem: My first page of the bibliography doesn't display the page number, like in this figure:

And you can see that the other pages display page number:

How can I fix it?

Answer 1

You can get \bibpreamble to do this for you:

\renewcommand{\bibpreamble}{\thispagestyle{myheadings}}

\bibsetup, as suggested in the comments, is only available if you use biblatex. I was going on a hunch that you're using the natbib package instead, which inserts \bibpreamble just before the reference list, after the Reference/Bibliography heading.

If you were not using natbib either, you may have had to use e.g. etoolbox to patch the thebibliography environment instead:

\usepackage{etoolbox}
\patchcmd{\thebibliography}
  {\chapter*{\bibname}}
  {\chapter*{\bibname}\thispagestyle{headings}}
  {}{}

though the exact patch would depend on the .cls you're using. I'm assuming the same thebibliography from book.cls here.
