Today all of my multisite domain mappings appear to have been lost. In the network-admin settings section for the domain mapper, I get a message stating something along the lines of, "You use old version of sunrise.php please move file from x to y". I followed these instructions, yet the message remains. Additionally, when I go to the "Mapped domains" section there are no domains listed.
I also noticed the layout for the add domain page is wonky. I cannot add a domain or edit them. There are no action buttons or a places to input a domain.
Is this a known or new bug? Are all of my mapped domains lost? This just happened today, and I have not recently updated any plugins that should affect this. Any help is appreciated.
