I lost domain mapping for my site, there was a message about adding sunrise.php to the wp-content folder. That's been done and I have also deleted the old domain-mapping out of the mu plugins, and copied an updated single file to the wp-content (as per the instructions in the update download).
But now I do not have anywhere in the new wordpress to update the domain-mapping settings. Before it was under tools, but now it doesn't exist anywhere. Not in the Network Admin area of wordpress, and not in each of the individual sites.
There is an oddity, that domain mapping is working for the base url of any of the sites, but it doesn't work for any links from those pages (also logins seem a bit skewif as well)
I can't find anywhere to check/change these settings. I am running the latest wordpress to date (3.5.x—I only just finished the update).
