Hey, I just set up a 256 DB version of Multi-DB. on WPMU v2.6.3 using the latest control
Man, that was a LOT of work
As my last step I copied over db.php and db-config.php
Now it's dying in wpmu_settings.php function wpmu_current_site
die( "No WPMU site defined on this host. If you are the owner of this site, please check Debugging WPMU for further assistance." );
At that point I echoed out the following vars
When I rename db.php to db.ZZZphp it all works fine again.
I am using a lot of domain mapping.
Any ideas what to check next?
