Alright so, I manage 9 different wordpress sites for academic and business purposes. Recently we updated to 3.2.1 on all of our networks. I've tried three of these networks now, and I can't add a new site to users.
The way I've always added sites to users, is when they register on the site, I go to network admin -> sites -> add new -> and I copy their email from their registration information, I title the site for them, and I give it a URL and hit add.
Up until 3.2.1, that worked. Since the update, every new site just comes up with "Error establish a database connection" and it happens across all our sites (several of which aren't connected by the way).
I've tried disabling all plugins, and that doesn't help. I've tried reinstalling wordpress and That doesn't help. Could I be missing something??
