When I run the script below with Quick Build it picks up very old versions of the .bib file chap2.bib that is long since gone
\documentclass[11pt]{book}
\usepackage{tgpagella}
\usepackage{lmodern}
\usepackage[natbibapa]{apacite}
\begin{document}
\input{chapter2}
\bibliographystyle{apacite}
\bibliography{chap2}
\end{document}
I have tried many times using the {Latex, Bibtex, Latex, Latex} formula. It makes no difference.
There's a similar question answered on 22 Nov 2017 by Danilo Gregorin to a post entitled 'TeXMaker doesn't recognize updates in the .bib file', but I don't know how to set the path he suggests in MikTex.
Does this work if you set the path as suggested or are there any other suggestions?
pdfLaTeX+BibTeX+pdfLaTeX+pdfLaTeX, it might be your issue here. You can set your quickbuild to do that in TexMaker – RockyRock May 30 '18 at 06:35
