WordPress MU Domain Mapping
[resolved] Annoying mix of mapped domain and main domain in admin (3 posts)

    Hi all,
    I have been using Donncha's Mu domain mapping plugin for several years, but a few months ago it started to have problems (plugins would not (de-) activate etc).

    I just updated to both WP 3.2.1 & the newest map plugin (, but still some very annoying problems pop up:

    The domain is mapped ok: so newdomain.com shows up as newdomain.com which in reality is newdomain.maindomain.com
    When logging into the back end, the top of the admin page (right next to the small WP logo) mentions the tagline for the Newdomain, but below the Dashboard shows 'Right Now', Recent comments etc all for the main domain.
    (It shows 16 posts, while only one hello world post is created). Same happens for previously mapped domains.

    - When I click on the posts links (either in menu or in 'right now'), it shows me the correct lists of post for the mapped domain (newdomain.com/wp-admin/edit.php), but all posts just link back to newdomain.com/wp-admin/ without option to edit the post.

    - Similar problem: when going to settings-general, it shows the tagline of the main blog, not the mapped subblog. Though when I change it, it does make a change for the subblog, while not showing in the backend.

    FYI: On the main site, I have mapping options 2&5 marked:

    "Domain Options
    O. Remote Login
    X. Permanent redirect (better for your blogger's pagerank)
    X. User domain mapping page
    O. Redirect administration pages to site's original domain (remote login disabled if this redirect is disabled)
    O. Disable primary domain check. Sites will not redirect to one domain name. May cause duplicate content issues."

    What is wrong and how can I fix it?
    Many thanks!

  2. Have you tried eliminating other plugins?

    Thanks Andrea, I just found the culprit:

    bp-registration-options strangely enough creates this strange behaviour!


    I wonder if they are exposing some minor security leak as any subblog can see all basic but behind the scenes info of the main blog (theme, number of posts, taglines, active plugins etc)?

    Cheers, Harry
