Running texfilter, I get the following error message
1>The shell command
2>"/home/httpd/vhosts/scienceclass.nl/httpdocs/moodle/filter/tex/mimetex.linux" -e 3>"/home/httpd/vhosts/scienceclass.nl/httpdocs/data/filter/tex/0cfae383362bc63d7ac429a5755fef05.gif" 4>'\Large 1+1=2'
5>returned status = 126
6>Image not found!
7>Please try the debugging script
I suspect from the returned status, 126 (see 5>), that my host doesn't support shellscripts at all.
Where in the phpinfo() output can I find information to be shure of that?
