I am currently hunting for errors in my template and these two I cannot solve after reading the log and researching:

! LaTeX Error: Option clash for package hyperref.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.


The package hyperref has already been loaded with options:

I already ruled out

  • Bibliography-styles requiring it
  • Package not loaded last
  • Putting global hyperref options in Documentclass options (even more errors)

My current knowledge is that some package/configuration file loads/requires hyperref. Therefore I looked at the log-file. But as a beginner I cannot decipher (a) which package causes the problem and (b) how I can solve/bypass it.

Minimal example:

\documentclass[a4paper, 12pt, oneside]{book}

    ocgcolorlinks=false, %sample

    urlcolor=red, %sample

        \hypersetup{pdfpagelayout=TwoPageLeft, linkcolor=red}


This is a test.

Using your code, I don't get any error if I load bookmark AFTER hyperref. Try it. – Jubobs Mar 7 '13 at 14:27
You need to load bookmark after hyperref: 1. The clash doesn’t exist anymore. 2. bookmark re-defines some hyperref’s macros. – Qrrbrbirlbel Mar 7 '13 at 14:27
I can imagine that this would be hard to debug given the number of places where I've read that hyperref should be the last package you load. – Ethan Bolker Mar 7 '13 at 14:41
@EthanBolker Yes, but see also Which packages should be loaded after hyperref instead of before? And packages, which should be loaded after hyperref, often state this in their documentation. I know “often” is not “all”, though … – Speravir Mar 7 '13 at 21:14

Loading bookmark after hyperref solves the error.

See Bookmark-Documentation on page 7.
