I'm using natbib, setcitestyle packages and agsm style. I want to italicize words "et al" so that they appear as "et al".
I have located and changed the agsm.bst file (5 instances of et~al to **\emph{et~al}**) and placed it in the same folder as my work. I have also pointed the biography style to new bst file. However, I see no change in citations.
I'm using TexStudio and Windows 8. I have gone through previous posts concerning this issue without success.
Previous posts on this issue:
Using natbib and plainnat - no year appears to some references and also et al. not in Italics
How to typeset 'et al.' in italic with the agsm bibliography style?
..and many others.
Please help.
MWE:
MinimumWorkingExample.tex:
\documentclass[a4paper, 12pt, oneside]{Thesis}
\usepackage{natbib}
\setcitestyle{aysep={,}}
\begin{document}
Here is a minimum working example:
Single author~\cite{yeung2007reducing}. In the second line, we provide an example of citing more than 3 authors so as to test of the words et al are italicized~\cite{samadi2010optimal}.
\bibliographystyle{agsm}
\bibliography{MWERef}
\end{document}
MWERef.bib File:
@inproceedings{samadi2010optimal,
title={Optimal real-time pricing algorithm based on utility maximization for smart grid},
author={Samadi, Pedram and Mohsenian-Rad, Amir-Hamed and Schober, Robert and Wong, Vincent WS and Jatskevich, Juri},
booktitle={Smart Grid Communications (SmartGridComm), 2010 First IEEE International Conference on},
pages={415--420},
year={2010},
organization={IEEE}
}
@article{yeung2007reducing,
title={Reducing energy costs with peak shaving in industrial environments},
author={Yeung, Phillip},
journal={Schneider Electric, September},
year={2007}
}
Output:
Thanks for your comments guys. MWE works, but my thesis document still cannot italicize the words et al. I will have to look for conflicting packages in the thesis document because MWE contains fewer packages than the thesis document.

\emph{et~al}notemph(et~al)(\added and{…}instead of(…)). Have you runbibtexagain? And do you mean\setcitestylecommand? Can you please show us a minimal working example with bibliography and documentation of your changes? Currently we cannot reproduce the problem. – Schweinebacke Sep 02 '17 at 14:14agsmbibliography style, which is known not to italicize the string "et al". Have you tried the adjustments recommended in the linked answers? – Mico Sep 02 '17 at 20:31
