Cims has super funny permission settings on its public_html folders. I have a LaTeX in browser running there which is a very simple script. The real trouble was setting up the permissions. Here's the permissions of the containing folder, latex-in-browser/:

drwx---rwx   2 jacobson asj237        21 Mar 30 10:33 latex-in-browser

And of the relevant php files, latex-in-browser/index.php and latex-in-browser/typeset.php:

-rwx---r-x   1 jacobson asj237      4203 Feb  6 00:47 latex-in-browser/index.php
-rwx---r-x   1 jacobson asj237       795 Mar 30 10:33 latex-in-browser/typeset.php

Another thing that I found was the command in my typeset.php script:

  $output=`pdflatex -interaction nonstopmode -halt-on-error $texFile`;

was not being executed. But when I did

which pdflatex

and found the full path to pdflatex. Then

  $output=`[insert/full/path/to]pdflatex -interaction nonstopmode -halt-on-error $texFile`;

worked fine.
