I run WordPress on IIS 7.5 / Windows Server 2008 R2. All versions of PHP after 5.3.7 are exhibiting problems with some WordPress plugins, where 500 errors are thrown and no PHP log is generated, when using Windows Authentication to protect sites (anonymous authentication disabled). If I roll back to PHP 5.3.6 or earlier, the problems resolve. If I turn off Windows Authentication while using PHP 5.3.7 or newer, the sites and plugins work as expected. The problem is the specific combination of Windows Authentication, some WordPress plugins, and PHP 5.3.7 or newer. An example plugin problem: I get 500 errors when using WP Super Cache with WordPress on PHP 5.3.7 or newer. If I roll PHP back to 5.3.6, the plugin again works as expected. Test script: --------------- http://wordpress.org/extend/plugins/wp-super-cache/ Expected result: ---------------- I expect the WordPress plugin to work as designed. Actual result: -------------- I receive a 500 error when using the WordPress plugin on a site with Windows Authentication running PHP 5.3.7 or newer. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60787&edit=1
