I use the php script that I install with apache 2.2.. ( webuzo , centos 7, php 5.3 and apache 2.2)... But after I change to php 5.5, there is no problem I detected. But after change to apache 2.4... there were problem :Not Found
The requested URL /abcd ... was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Changing it to Apache 2.4 I got the same error what you are getting...
Changing back to Apache 2.2 , website started working but Permission of Files and Folder got changed and hence I started getting so many permission denied message on my website... Finally I had to reinstall...!
I think webuzo do not properly configure Apache 2.4
