I seem to be having issues on a fresh WPMU 3.4.1 install.
I'm getting no error messages on the plugin install--but Tools > Domain Mapping does not appear for any of my subsites in order to actually manage the domains. (They all have "Tools," just not "Domain Mapping").
"Domain mapping" configuration and "Domains" are options under superuser's settings, but that's it. Any domain I enter under superuser > Settings > Domains disappears and does not populate the db table.
Is this a 3.4.1 issue? Supposedly there's nothing in the latest WP update that should cause this plugin to behave differently than in 3.4.
Just to confirm:
--The wpmu is installed in my dev domain's root directory. I.e., I installed wpmu to http://mydevsite.com and not a subfolder of that domain (which I know won't work for domain mapping).
--I manually installed the plugin, uploaded sunrise.php to the wp-content folder, updated wp-config.php, and network-activated the plugin.
--I also set the IP in the domain mapping settings and dealt with the wildcard record on the server end, not that that should affect the issues happening.
--I updated the network.
Anyone else having this occur?
