Please guide how to fix? This is for NAACL conference format and works on overleaf. I am not sure why it breaks in arXiv: Here is a link to git repo of the code https://github.com/monajalal/WiNLP2018

    I don't think the warning you cite in the title is the problem. It is only a warning after all. There definitely is an error with LaTeX Error: Option clash for package hyperref. It seems you (or other packages you load) load hyperref twice with conflicting options. Don't do that. Load it only once. – moewe May 21 '18 at 5:59
  • I am not loading it twice though. I have checked. – Mona Jalal May 21 '18 at 18:17
  • @moewe I added all the files here can you please have a look at the git repo? github.com/monajalal/WiNLP2018 – Mona Jalal May 21 '18 at 18:23
  • Mhh, the document works fine if I compile it on my machine. Not sure what changes the arXiv applies. Maybe it is enough to remove the hyperref option from \usepackage[hyperref]{naaclhlt2018} for the arXiv submission. – moewe May 21 '18 at 18:48

The log here doesn't show the complete error message. The option clash for hyperref error is arXiv's ad hoc application of hyperref to all submissions (unless explicitly disabled by the user), and not related to the natbib issue that is in question.

I also see that this submission has expired, so if you're still having trouble, please upload the files to arXiv again, and ask for help via help@arxiv.org.
