Getting 500 errors when adding new question. Why?
My server is throwing 500 errors whenever I try to add a new question. This issue is happening on multiple subdomains of mine, and I have already checked the file permissions, and replaced the post-new.php with the default one. I have also tried deactivating all other plugins, and the plugins I am using are up to date. The error it is throwing me is below:
[Tue Sep 29 18:25:07 2015] [error] [client 173.227.74.5] Premature end of script headers: post-new.php, referer:http://asdf.chatterhorn.com/wp-admin/

Any ideas on why this might be happening and how to fix it?
