WP 3.1.3 multisite, Domain Mapping 3.0.4, other plugins include marketpress, membership.
Permalinks set to Day and Name.
head site is domain1.com which has some pages and a custom menu.
subsite 1 is domain2.com which also has pages and a custom menu.
subsite 2, 3, 4 ditto
The problem is that the links from the menu on subsite 1 etc all say they are linking to domain2.com etc but in fact try to load the main page of domain1.com.
Is this a permalinks issue?
Or do I need some other menu manager?
