ispconfig 3.0.4.6 functioning but not writing bind config files

[ronee]

Running ispconfig 3.0.4.6 on CentOS 6.3, all appears well however primary and secondary zones added within ispconfig do not get written to bind config files and therefore the server is not authoritative for any zones.

Am running many ispconfig 2 and 3 servers, am a bit baffled by this one.

/var/log/messages doesn't show much related to bind other than lines like these whenever bind is restarted:

named[9204]: error (network unreachable) resolving 'isc.org/
ANY/IN': 2001:500:2c::254#53

Recursive queries are enabled so the server is simply non authoritative for zones it should be authoritative for.

Any input would be of interest.
