I know little about php so I acquired a script off the web to include a "spam-free" form on one of my websites which is *not* on a Zen server. The script works fine.  However, when I transfer it to one of my other websites which *is* on a Zen server (Linux Bronze package), the script will not run. I have looked at this thread - http://forum.zensupport.co.uk/thread/29873.aspx - and followed the instructions in the last post i.e. amending the .htaccess file to include:

AddType application/x-httpd-php4 .xml
AddHandler application/x-httpd-php4 .xml
(also tried php5)

It still won't run. Any advice would be greatly appreciated. Thanks
