seems to be a bug in mydns:
http://www.howtoforge.com/forums/sho...t=32145&page=2
from falcontx:
The problem is that the query is looking for "active=1" in the dns_soa table. However, in ISPConfig 3.0.1.1 (and probably the SVN, as well), the "active" field in the dns_soa table is type "enum('N', 'Y')", so that query will always fail.
this thread solved the issue.
