I'm in the process of building out a new WordPress Multisite network on a dedicated hosting environment I just purchased. I am running into an issue where every time I create a new site on the Network(and it happened when I did the original 5-minute install of WordPress as well), I receive a 500 Internal Server Error when WordPress starts to refresh the page.
However, the strange thing is that when I go back into the admin system, everything is there and has been created properly as if the error never existed. The apache logs are telling me that the following error is occurring:
[Sun Jan 13 16:21:45 2013] [error] [client 18.104.22.168] malformed header from script. Bad header=/var/www/vhtdocs/userweb1/dead: site-new.php, referer: http://kether-interactive.ca/wp-admin/network/site-new.php
I'm not sure where to go about starting to troubleshoot something like this because I'm not really a server admin. Anyone have any thoughts? Is there a php module or something that I might be missing?
