PHP has no $_POST values

Hi,

Ive got an odd situation. Ive been developing a new page / section to
my website (PHP / PHP Smarty templates)

A week ago, it was working fine for this particular script, But today
when i revisit it, there's NO $_POST values being received by the
script at all.

Other scripts in the same directory, work fine. Ive created a
sub-directory and moved the scripts (included files & main script for
the one I'm working on) into the subdirectory and still no $_POST
values.

The top of my script looks like this (no other information or processing)


error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);

 echo "<pre>1\n".print_r($_POST,true)."</pre>\n";

RESULT = a blank/empty array.  Other scripts in the directory (now
parent directory) work fine.

Does anyone have ideas on what may be preventing the POST values ?

PS the htaccess file only contains 2 lines :-

RewriteEngine on
DirectoryIndex provisional.php

QUESTION 2:- Are there any instructions on how to use this php forum ?
I'm getting NO information at the footer of these messages - archive ?
how to change settings etc ?
