We are building a multi-site AND multi-domain website.
We did install everything on a testing server with names like
and so on... everything was fine.
Then we moved everything on a production server and used a search and replace script to update the whole WordPress database with the new names
site1.lan -> protestant.wng.ch
site2.lan -> eerv.wng.ch
site3.lan -> epg.wng.ch
In the "Multi-Domain" settings page, the Wildcard availability displays "unavailable" for eerv and epg but is ok for protestant.
In our DNS server everything looks ok for all the domains as we have CNAMEs for *.
If we add a new domain there, the wildcard is ok right after the creation.
I tried to delete one entry and re-create it but it's still "unavailable"...
Do you have an idea of how we can rename correctly domains in those kind of installations ? And by the way correct our problem ?
