Support » Plugin: WordPress MU Domain Mapping » adding new mapping doesn’t work anymore

  • Resolved Fissunix


    i have 5 sites mapped for some times now. I’ve just added one more recently, everything seems fine (DNS, ping and setup) but mapping doesn’t occur. Anything i should know to make it work ? (using WordPress 4.9.8)

    I have the same issues. 7 websites are working perfectly. i added a new one however it doesn’t map correctly.
    Are you able to figure it out?




    it looks like the plugin still works for me (folder setup) when i add a website.
    There was a thing missing on a DNS level, when fixed, the mapping worked just fine.

    Hello, Fissunix
    am getting this error when setting up the mu domain mapping plugin “Please edit your /home3/mysite/public_html/wp-config.php and move the line define( ‘SUNRISE’, ‘on’ ); above the last require_once() in that file or make sure you updated sunrise.php.”

    I have edited the wp conf.php, as instructed, moved sunrise.php to wp-contents folder, yet am getting the error still

    @fissunix @michelabikhalil, what did you do to resolve this? I am having the same issues. Existing MU sites are mapping perfectly fine but I just added a new site and it won’t map. All my DNS, A records, hosting, etc., are fine but when I visit the url, it just says “page isn’t working” empty response. I am running latest WordPress 5.0.2.

    On that note, I heard there may be a native domain mapping feature hidden somewhere in WP 5.0 but can’t find much info on it.
