I am using elsarticle
Everything was find before I used \usepackage{arabtext}.
When I compiled to PDF, I got the following error message.
And if I type "s", everything became fine again but I don't want to type an "s" every time I compile PDF preview.
Please anyone advise.
Thank you very much in advance for your help.
Here is the code
\documentclass[12pt, authoryear]{elsarticle} % use "amsart" instead of "article" for AMSLaTeX format
\usepackage[colorlinks=true,linkcolor=black, citecolor=blue, urlcolor=blue]{hyperref}
\usepackage{geometry} % See geometry.pdf to learn the layout options. There are lots.
\geometry{a4paper} % ... or a4paper or a5paper or ...
%\geometry{landscape} % Activate for rotated page geometry
%\usepackage[parfill]{parskip} % Activate to begin paragraphs with an empty line rather than an indent
\usepackage{graphicx} % Use pdf, png, jpg, or eps§ with pdflatex; use eps in DVI mode
% TeX will automatically convert eps --> pdf in pdflatex
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage{tipa}
\usepackage{arabtex}
