Hi All, I followed the guide at [http://www.tjitjing.com/blog/2006/05/php5-with-iis6-on-windows-server-2 003.html] to get a manual install of PHP 5 on our Small Business Server in the office. IIS will serve pages with basic PHP - echo 'hello', phpinfo() etc. but when I point a browser at a page with MySQL database connection nothing is sent to the browser at all, just a blank page with no code in the source. The page I'm trying to see is a working page that runs fine in a live environment both on a dedicated box running linux and a shared box running windows. I have turned on the show error display in php.ini and enabled error logging but on the office server no errors are displayed or recorded when the blank page is served. If I try to call a page with just include('doesn't-exist.inc'); the usual 'invalid file name' error is shown by the php engine and the rest of the page renders as expected. Can anyone advise where I need to be looking to try and track the source of the error? Thanks, Chris.
