we have a multisite install width the following structure:
Where "pages" is blog 1.
Other site in the network have domains like:
All works fine. We can reach every site in the network and work on it.
If we make an update, all sites point to the main site "*://domain.com/pages/" and not the domain which was set in the backend.
This happens only after the upgrade. The htaccess, Domain Mapping or the sunrise.php are not being changed during the update.
Deactivating all Plugins, also does not help.
I did not make the install.
Does anybody have an idea, what the issue could be?
Many Thanks in avcance, Lars
