• your example produces a different error to the one you ask about ! Too many }'s. l.1882 \let\fi\fi} {}% ?  (it would be helpful if you removed all packages unrelated to the error) – David Carlisle Jun 12 at 19:16
• is there any reason to suppose that natbib and apacite can be loaded together? If I comment out apacite than the document is error free – David Carlisle Jun 12 at 19:17
• Further to the coment from @DavidCarlisle, it's best to load only the packages that you actually need, and avoid loading the same package more than once. I can't think of any reason to load both color and xcolor, or both url and hyperref. – Ian Thompson Jun 12 at 20:03
• actually apacite has a natbibapa option to "allow a little compatibility" with natbib (see the apacite manual) – David Carlisle Jun 12 at 20:05
• I still get the error, even if I delete apacite \usepackage{natbib} \begin{document} hi \bibliography{references} \bibliographystyle{unsrtnat} – Theresalue 2 days ago
