itemize cannot nest if enumitem is included before some package [closed]

Question

Nesting itemize was working until I usepackage{enumitem}. Now it doesn't work.

Answer 1

The problem was inclusion order.

\usepackage[ruled,vlined]{algorithm2e}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{bm}
\usepackage{cancel}
\usepackage{threeparttable}
\usepackage{fixltx2e}
\usepackage{MnSymbol}
\usepackage[stretch=10]{microtype}
\usepackage{multirow}
\usepackage{paralist}
\usepackage{units}
\usepackage[shortlabels]{enumitem}

One of these packages must be included before enumitem.
