Thank you.
- Your file permissions are not correct … As I said, the permissions check on the host shows all permissions are correct.
- You are out of space on your hosting… My reseller hosting comes with unlimited space. The website in question is a tiny new development.
Honestly, if either of those was the problem, I wouldn’t have had to ask the question here because they’re the first things I’d look at during my own diagnosis. Point 1 especially, since the error report mentions file permissions.
Any other ideas?
Further info. WordPress version is 3.9.1
