Undefined control sequence \EnableCrossrefs

Question

I'm having some trouble with this. I'm quite new to LaTeX, and I'm just trying to recreate a word document in LaTeX. Here's the full error:

E: c:/texlive/2016/texmf-dist/tex/latex/colordoc/colordoc.sty:155 Undefined control sequence \EnableCrossrefs

And here's my preamble if that helps at all:

\documentclass[letterpaper,12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{titling}
\usepackage{blindtext}
\usepackage{subcaption}
\usepackage{placeins}
\usepackage[margin=1in]{geometry}
\usepackage{enumerate,amsfonts,amsmath,amssymb,multicol,amsthm,multirow}
\usepackage{graphicx,epsfig,dashrule,colordoc,fancyhdr}
\usepackage{tcolorbox} %% to put boxes 
\usepackage{float}
\cfoot{\thepage}

Thanks for any help.

If you must use the colordoc package -- and you almost certainly need not -- you should also load the doc package, like this:

\usepackage{graphicx,dashrule,doc,colordoc,fancyhdr}

(The doc package defines the \EnableCrossrefs macro.) My recommendation, just in case it's not clear, is to load neither the doc nor the colordoc package.

Whatever else you do, don't load the epsfig package -- the more so since you're already loading the graphicx package.
