I've written a journal paper of 27 pages in two columns style. In 26 pages there is a space between the two columns, and only in one page they come side by side without any space. Does anyone have an idea how to solve this issue?
\documentclass[twocolumn]{article}
\usepackage{lipsum}
\usepackage{graphicx}
\usepackage{epstopdf}
\usepackage{fix-cm}
\usepackage{siunitx}
\usepackage[labelfont=bf]{caption}
\usepackage{floatrow}
\usepackage{lipsum}
\usepackage{subcaption}
\begin{document}\sloppy
\lipsum
\end{document}
\usepackageif the package that is no longer used, keep doing that until you have an example small enough to post. – David Carlisle Mar 21 '18 at 17:15
