I have a sneaking suspicion it is selinux chucking a fault on labels...
I'm certainly no expert on selinux but it sounds like apache doesn't
have permission to read the files or filesystem you are trying to feed
it.

Are there any messages in the audit log?  "ausearch -i -start recent"
may give you a clue, or it may be in "journalctl -b" if audit is not
enabled.
