WordPress MultiSite & sunrise.php

Are you getting the above error message as well?

After doing a fresh install and enabling multi-sites I couldn’t see the Domain Mapping and Domains sub-menu options under Network Admin / Settings.

I loaded up my trusty editor and confirmed

define('SUNRISE', 'on' );

was in fact in the file. It was slightly higher than where it said, it’s not important, but I moved it anyway, and I still got the error.

I checked and sunrise.php was in fact in the correct location under /home/public_html/wp-content/sunrise.php

So how did I fix it?

The problem was, it was the incorrect (read:old??) sunrise.php file!

Copy the correct one from:

/home/public_html/wp-content/plugins/wordpress-mu-domain-mapping/sunrise.php

and replace the previous one, and reload your admin page. You will now see the welcoming domains page :D

If you want to find out more as to why it happened, and how it is that my sunrise.php got “moved” or “re-moved”, it was due to a conflict by domain mapping plugins. I’ll be blogged about it in the near future and it will appear here (currently in draft and not published).
