I have seen that a lot was already written on the error-message "destination with the same identifier (name{page.})". However in my case, no solution does the trick.
Here is a MWE that should replicate the mistake:
\documentclass[10pt,oneside,onehalfspacing]{book}
\usepackage[a4paper,margin=3cm]{geometry}
\usepackage{setspace}
\setlength{\parskip}{0.5em}
\usepackage{fancyhdr}
\pagestyle{fancy}
\usepackage{xcolor}
\usepackage{wasysym}
\usepackage{fixltx2e}
\usepackage[toc,page]{appendix}
\usepackage[natbibapa]{apacite}
\usepackage[nottoc]{tocbibind}
\usepackage{graphicx}
\usepackage[strings]{underscore}
\graphicspath{02\_images}
\usepackage[utf8]{inputenc}
\usepackage{csquotes}
\usepackage[plainpages=false,pageanchors=false,hidelinks]{hyperref}
\begin{document}
\chapter*{Declaration Of Authorship}
\pagenumbering{roman}
Some example...
\chapter*{Statement Concerning Publication}
Some example...
\chapter*{Acknowledgement}
Some example...
\pagenumbering{gobble}
\tableofcontents\thispagestyle{empty}
\chapter{Introduction}\label{Intro}
\pagenumbering{arabic}
Some example...
\chapter{Theoretical Framework}\label{TF}
Some example...
\chapter{Findings}\label{Fin}
Some example...
\chapter{Conclusion}\label{Con}
Some example...
\end{document}
I assume that the mistake comes from \hyperref but the follow solution does not do the trick:
\usepackage[plainpages=false,pageanchors=falsehidelinks]{hyperref}
The Pdf-File seems to be fine, but the error bothers me...
pageanchors=falseas an option. The question is however, if the anchors are still correct, i.e. the linking leads to the correct position – Mar 30 '16 at 22:50pageanchor=false, notpageanchors, that fixes the problem for your MWE (at least), sorry about that. Butfixltx2eis deprecated, since all features have been incorporated into the LaTeX core. – Mar 31 '16 at 09:13fixltx2eand did some other alterations, too. The mistake is gone though. – Flavio Frei Mar 31 '16 at 11:50
