Did you disable AppArmor?
You don't need to rush to disable AppArmor. It is very easy to detect if AppArmor is causing a given problem. Just run "grep APPARMOR /var/log/audit/audit.log" and if AppArmor has blocked anything, it will say so there. If you get nothing back from that search, then AppArmor is not your problem, no need to disable it, your problem is elsewhere.
If AppArmor *does* have an issue, you can also quickly fix it by running "logprof" as root, and AppArmor will offer to update your profiles to permit whatever the problem was to happen.
