# a very weird situation for the Latex Error: Something's wrong--perhaps a missing \item

I am using classicthesis download from latextemplate. It has main.tex and chapter01.tex. etc.... I got this error "Latex Error: Something's wrong--perhaps a missing \item" when I was writing in chapter04.tex. The log pointed me to the main.tex where the \include{chapter04} command is. I guess this is more complicated than just changing anything about this line.

Plus, I had not come across with any error before when I compiled main.tex with Chapter04. What made it REALLY weird is when I just randomly comment out (or delete) a paragraph in chapter04 or just change the font from 11pt to larger ones like 15pt, the error disappeared and main.tex compiled OK. It just seemed I have certain length (after typeset) of this chapter that Latex is not happy about...

I really dont understand this. since there are multiple files related to the issue and I frankly dont know which one went wrong or have conflicting issue, I just uploaded the zip folder containing all the relevant files.

a dropbox link to my files

I would really appreciate any help for this urgent issue in my thesis writing.

• Hello and welcome to tex SE. Please provide a minimal example showing your problem. Jul 11, 2014 at 18:09

You cannot have \\ in a section title using this documentclass.

works:

\section{How do lithium ions interact with OIPCs? --- A  Molecular Dynamics study}


doesn't work:

\section{How do lithium ions interact with OIPCs? \\ --- A  Molecular Dynamics study}

• It depends on the document class. That is, on how \section is defined and possibly also how headers are defined and how the table of contents is defined. A \ in a section title can often work fine, but it does seem to be the source of the error in this document.

• Is any way to have a line break in the section head? Jul 12, 2014 at 1:45
