I tried to browse to the index.php file and got permission denied. Other mods were browsable, but not the new one I was trying to install. Knowing that OS permissions were set correctly, I simply disabled selinux with setenforce 0 and then it all worked. Now I knew it was SELinux and then I just had to reset SELinux security for the new folders.
I never turned on debugging, just tried browsing to the files.
