I have changed my pc and installed full package of latex "texlive-full". But when I ran the code I got the error as follows
Command \@xhline has changed.
Here is the first part of the tex file
\documentclass[12pt]{iopart} \usepackage{iopams} \usepackage{graphicx} \usepackage{graphics} \usepackage{subfigure} \usepackage{multirow} %\usepackage[ %singlelinecheck=false % <-- important %]{caption} \DeclareMathAlphabet\mathbfcal{OMS}{cmsy}{b}{n} \usepackage{booktabs} \usepackage{cite} \usepackage{longtable} \usepackage{pdflscape} \usepackage{graphicx} \usepackage{floatrow} \floatsetup[longtable]{LTcapwidth=table} \usepackage{array} \newsavebox\dummy \newcolumntype{H}{>{\begin{lrbox}{\dummy}}c<{\end{lrbox}}@{}}
This tex file is working on my old pc. What is the problem ?
