I was at WordPress 3.1 with MU Domain working just fine. After I upgraded WordPress to 3.3.1 it stopped working, so I upgraded the MU plugin to the latest version 0.5.4.2. This seemed to resolve some, but not all of the problems.
The site has a Parked domain MU WordPress install in the main directory and a separate add-on domain installed in a sub directory. This parked domain site, in the main directory is hosting sub domains for another primary site which is at another hosting provider (GoDaddy). I want to move away from GoDaddy and was putting all the new sub-domains for the GoDaddy primary site under the BlueHost account.
This is the setup:
JDSolarSolutions.com -> Primary parked domain at BlueHost Dedicated IP 126.96.36.199
ClimbForAChild.org -> Add-on domain in a sub directory of the same hosting account.
wahockey.photoadventureswithed.com -> Sub domain under the MU site of JDSolarsolutions.com, This is the one with the primary domain over at GoDaddy.
There is a DNS A Name record at GoDaddy which points wahockey.photoadventureswithed.com to 188.8.131.52 at BlueHost.
Prior to the upgrade, this used to get me to the correct sub-domain site, after the upgrade it gets me to the ClimbForAChild.org add-on domain??
I have tried every trick I could find in the posts but I seem to be missing something. I tried network deactivate and reactivate of the plugin, going back to the old version of the plugin, editing the site URL in the Network Admin panel, making the sub-domain non-primary and changing the A Name record to a C Name record. All with no luck.
I don't know what setting I lost during the upgrade, but could sure use some help.
