I’ve been trying it on a clean install and keep getting the same problem: the network admin dashboard stats won’t budge. They’re stuck at “You have 1 site and 1 user” even after adding a second site and a second user.
That’s on an Nginx-based server, but I have a similar problem on my local PC, which is running Apache – although, in this case, it says “You have 4 sites and 4 users” when I actually have 5 sites and 4 users.
On another Nginx-based server, I don’t have the problem at all, although it may appear when I add a new site.
If it helps, I just noticed an error message on my main test site’s dashboard saying “The plugin wordpress-mu-domain-mapping/domain_mapping.php has been deactivated due to an error: Plugin file does not exist”. But the file does exist and, without me doing anything, the message disappeared and, having checked the network dashboard, the plugin is still active as a must-use plugin. Strange.
If I sent you the logon details, would you mind looking into it on my server?
