I have recently moved over some apps from a PHP 4.x installation to a PHP 5.0 installation. The php.ini file needed some changes which I have done and the applications ran well for a month, being served out of a Win 2K IIS Web Server.
Suddenly, a few days ago, on IE 6.0 and Netscape 7.2, when I type in the URL for an HTML page or a PHP page, instead of accessing the page from the webserver the File Save As or a Download Manager dialog is being displayed asking if the PHP script should be downloaded (!!!) The HTTP headers are not including the Content-Disposition for the script. And the file in the Cache is being displayed. Happens even after clearing the cache.
Any suggestions how to get this back to normal?
