I am getting this error which points to the input line where \maketitle is. The error goes away once I remove my \title{}. The code is down below:

Note: I am using overleaf.








The errors are:

Package xcolor Error: Undefined color `'.

See the xcolor package documentation for explanation. Type H for immediate help. ...

l.31 \maketitle

Try typing to proceed. If that doesn't work, type X to quit.

main.tex, line 31 Package hyperref Warning: Ignoring empty anchor on input line 31.

main.tex, line 31 Overfull \hbox (123.62721pt too wide) detected at line 31

  • @Robo0110 Please provide a Minimal Working Example `` MWE` that starts with \documentclass and ends with \ `\end{document}, that compiles and shows the problem.

  • Using recent MikTeX installation on my PC I can't reproduce your problem. You should contact Overleaf support.

I solved it by using \title{mode=alt} instead of just \title
