In my account, ConTeXt works no prob, I got a perfect PDF.
My problem occurs when I run ConTeXt via web, under Apache's user of course.
How to trace ConTeXt run under web server ?

No cont-sys.tex file on my ConTeXt installation. I have only
texmf-local/tex/context/base/cont-sys.ori &
texmf-local/tex/context/user/cont-sys.rme and they are original of
distribution (exactly like
http://source.contextgarden.net/tex/context/base/cont-sys.ori and
http://source.contextgarden.net/tex/context/user/cont-sys.rme )

The \write18{} feature was disable on my system.

Yes, you're right.

No problem, but firstly I need a running ConTeXt via web :-)
