    Hi,
    I think I’m using version 4.4.1, because the problem appeared just after I did a WP update, just a few days ago. I also updated the pluggins at the same time.
    When I access my website using Google, I can access the home page, and the first page of every tab. Each tab leads to a page where there are links to other pages: that where trouble begins. I receive messages like these ones:

    Warning: Cannot modify header information – headers already sent by (output started at /home2/edithbru/public_html/wp-content/themes/twentytwelve2-child/functions.php:2) in /home2/edithbru/public_html/wp-login.php on line 387

    I also get similar messages when I try to loggin (which is why I cannot verify the version I’m using. The website was working perfectly well before the updates. I’m quite novice and don’t know what to do from there…
    Here is the address if it can help: edithbrunette.net
    Thank you very much for your help.

  • FTP into your site and rename your twentytwelve2-child theme to something else and you should be able to get in and have the error stop. If it’s throwing that error, then it’s a compatibility problem with the child theme, I’m guessing. Try it. Your side will come up using the default theme.

    Can you give a little more detail please about how to rename the theme via FTP? I have a very similar problem and can’t get into my site.
    Thanks

    Thanks CyberCobre,
    I could enter my site. It “works” (I mean the infos are there and the links fonction) with the original theme, but of course it’s disgustingly ugly and messy. So then I renamed my theme with the previous “twentytwelve2-child” name. I guess the whole point was simply to access my WP, right?
    So I do have WP 4.4.1 installed.
    I have a dozen pluggins installed: I tried to uninstall each of them,one at the time, but the warning message still appears.
    I also updated theme twentytwelve.
    Any suggestion?

    I found a tread where someone suggested to replace the fonctions.php in the childtheme with a fresh copy. For some reason, it seems to work.

    Hopefully resolved.
