Option Clash for Hyperref Package with the Report Document Class [closed]

Question

I know hyperref is a problematic package and there are many discussion on how to avoid potential problems.

However, in this small piece of code, I am not event loading any package, and yet, I get the option clash error for the hyperref package.

Can someone please help me figure out what the problem is? If I can get this one to work, I will try my main document with many packages!

\documentclass[12pt]{report}

\usepackage{hyperref}
\hypersetup{urlcolor=blue}

\begin{document}

\chapter{chapter one}
Figure \ref{fig1} shows ...

\begin{figure}
\centering
FIGURE HERE!
\caption{caption for figure one}
\label{fig1}
\end{figure}

\end{document}

Answer 1

The option clash error requires that the same package is loaded twice. The second time with at least one new option that was not given at the time, when the package was loaded first (LaTeX loads a package the first time, at subsequent loading requests it only checks the options).

Only one package is specified by the example file, thus the second load request has to be in an automatically loaded configuration file. Since option colorlinks is not given, the only configuration file is hyperref.cfg. Perhaps you are using \usepackage[...]{hyperref} there to set some options. That's pointless, LaTeX does not load the package twice. Use \hypersetup instead.
