WordPress Site does not load, PHP Error.

[Ironman]

Okay guys, I have a WordPress website which was working perfectly fine last night. But when I checked it today I am receiving this error:

Code: [Select]

Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0

Fatal error: Unknown: Failed opening required '/home/xxxxx/public_html/wp/index.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in Unknown on line 0

I tried changing the permissions on index.php from 644 to 755 to no avail. I have back up for my WordPress site but, I have done some work to some pages which have not been backed up.

Any help would be greatly appreciated.

My site is working now. It's an issue with the chroot environment and my hosting service ran script is to fix it. They didn't update the service status notifications, so I thought it was an issue on my end.
