>Example Code from modules/projects/addedit.php:

><?php
>##
>## Files modules: index page re-usable sub-table

>
>require_once( "$root_dir/classdefs/date.php" );
>$df = $AppUI->getPref('SHDATEFORMAT');
>$tf = $AppUI->getPref('TIMEFORMAT');

>******

>As you can see nothing happens before the require_once function is called

>Please check the vendor's website for new patches.

>As a temporary solution, create a .htaccess file that contains 'Deny from 
>all'.
>Place it in the /modules/ directory and that should block remote users from
