Since you can't see your website, you probably won't mind rebooting your server.
I would recommend the following course of action - it's fully automatic:
Temporarily pasify SELinux - will allow your server to work, but without SELinux protection.
From the SELinux man page: "The best way to relabel the file system is to create the flag file /.autorelabel and reboot."
I hope this gets you out of difficulty.
