General ⇒ Command 'caption@box'

[mimi04]

I am using packages and document class at preamble and at running time, latex editor gives following error. No idea what is happening:
'''''! LaTeX Error: Command \captionbox already defined.
Or name \end... illegal, '''''

This can be a conflict of the caption package with your document class. Which document class are you using?

Stefan

\documentclass[12pt,twoside,a4paper,english]{book}

And what is your document code, preamble, up to \begin{document}?

And what is your document code, preamble, up to \begin{document}?

Stefan

\captionsetup[subfigure]{labelfont=rm}
\usepackage{fancyhdr}
\headsep = 1.0cm
\renewcommand{\headrulewidth}{0.2pt}% Default \headrulewidth is 0.4pt

\begin{document}

[Stefan Kottwitz]

The document class line and you code brings the error:

Code: Select all

! Undefined control sequence.
<recently read> \captionsetup 
                              
l.2 \captionsetup
                 [subfigure]{labelfont=rm}

The command \captionsetup is unknown. That's because you did not load the caption package. Add

\usepackage{caption}

before \captionsetup.

There's no error in this code.

Can you post the .log file, as attachment here? The attachment link is below the text edit field, when writing a post.

.log file is as follows:

Do you have a file caption.sty in your document directory? If yes, then delete it or rename it. Seems there is an old version. From the .log file:

Code: Select all

(caption.sty
Package: caption 2012/02/19 v3.2f Customizing captions (AR)

("C:\Users\...\AppData\Local\Programs\MiKTeX 2.9\tex/latex/caption\caption3.sty
"
Package: caption3 2018/09/12 v1.8c caption3 kernel (AR)

First, a current caption package would print "Package: caption 2019/09/01 v3.3d Customizing captions (AR)". Second, there is no C:\Users\...\AppData\Local\Programs\MiKTeX 2.9 path for caption.sty.
