I am trying to install WP MU on a fresh server (no current or previous WP installs on it) that is only running Apache 2.2, PHP 5.3.2, and MySQL 5.1.45. It's a virtual machine running win2k3 SP2. Mod_rewrite is on. I set up my vhost as localhost.localdomain.
When I fill out the wordpress mu install page and click submit nothing happens for a while, then I get a blank screen for http://localhost.localdomain/index.php.
When I check my Apache access log I get this msg (occurs exactly when I click submit): "POST /spipe/pkg?AgentGuid={41339692-BA1E-4FEF-B64E-68730ECE34A7}&Source=Agent_3.0.0 HTTP/1.0" 404 207
The only thing I can find is that it is a buffer overflow. What is it doing here? I am stumped.
