I declared my document in this manner and have been working successfully with it for a while.

\usepackage[colorlinks, linkcolor = black, citecolor = black, filecolor = black, urlcolor = blue]{hyperref}


But I think either since trying to use \textsubscript in the acronym section or working on the labels for some graphics I receive:

! Missing \endcsname inserted.
<to be read again> 
l.43 ...rfl\IeC {\"a}chenzustandsdichteverteilung}
The control sequence marked <to be read again> should
not appear between \csname and \endcsname.

! LaTeX Error: Missing \begin{document}.
See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
l.43 ...rfl\IeC {\"a}chenzustandsdichteverteilung}
You're in trouble here.  Try typing  <return>  to proceed.
If that doesn't work, type  X <return>  to quit.

! Extra \endcsname.
\AC@newacro ...fter \gdef \csname fn@#1\endcsname 
l.43 ...rfl\IeC {\"a}chenzustandsdichteverteilung}
I'm ignoring this, since I wasn't doing a \csname.

! Missing \endcsname inserted.
<to be read again> 
l.44 ...nimale Oberfl\IeC {\"a}chenzustandsdichte}
The control sequence marked <to be read again> should not appear between \csname and \endcsname.

The extra and missing endcsname repeat on and on. And since I started my document with \begin{document}, I'm not sure how to fix this. Would greatly appreciate your help and input

Hi and thanks for your quick responses. I cleaned up my code and removed all "Umlaute" from the labels. Are there other places where I shouldn't use them? The check for "flächenzustandsdichteverteilung" showed that it was once in my acronym section and once in the text. Both are gone. Now the compiler runs a litte longer but unfotunately still shows the same error.

  • Hi and welcome, does the above code give any errors? Works fine on my machine. Is your document latin1encoded? Comment out packages ucs and inputenc and add \usepackage[latin1]{inputenc}. – Johannes_B Nov 25 '14 at 15:36
  • Do not use umlauts in labels, it is bad. Really reallt bad. – Johannes_B Nov 25 '14 at 15:38
  • It compiles fine on my machine too. Btw, why do you load wrapfig, hyperref and url twice? – Bernard Nov 25 '14 at 15:42

    Obviously you used flächenzustandsdichteverteilung somewhere where shouldn't have done it. So search in your code for suspects. – Ulrike Fischer Nov 25 '14 at 16:00
  • You shouldn't use geometry with scrreport, by the way. And if your document is UTF8 encoded, use utf8 rather than utf8x if you are using a language which allows it. – cfr Nov 26 '14 at 1:23

Finally got the problem fixed: The problem was that my document used ISO-8859-x codification, but ShareLaTeX only supports utf8. So I took out \usepackage[latin1]{inputenc} and replaced it by \usepackage[utf8]{inputenc} Thanks a lot again for your support
