1. Reason
Error directive server-status in the Apache’s configuration file httpd.conf
2. Fix:
Edit the file httpd.conf
vi /usr/local/apache/conf/httpd.conf
Find and comment out (or add if not exist) the following code:
<Location / server-status>
SetHandler server-status
Order deny, allow
Deny from all
Allow from 127.0.0.1
</ Location>
