Invalid argument / Cannot modify header information

  • Hi everyone…
    I hope you are well.
    I am a wordpress rookie, don’t know much about PHP at all so I am hoping that someone out there can be good enough to explain in simple terms what I need to do to fix the site I am administrating. I have spent a while googleing the problem but it seems there are multiple solutions.

    My site is located at: https://www.measuredrecords.com
    I haven’t made ANY updates or edits to the site in a while, but all of a sudden is it displaying the following error:

    Warning: Invalid argument supplied for foreach() in /home/measuredrecords/wordpress/wp-includes/classes.php on line 92

Warning: Cannot modify header information - headers already sent by (output started at /home/measuredrecords/wordpress/wp-includes/classes.php:92) in /home/measuredrecords/wordpress/wp-includes/pluggable.php on line 391

    Line 92 of the classes.pho file is:

    $request_match = $req_uri . ‘/’ . $request;

    and line 391 of the pluggable.php file is:

    header(“Location: $location”);

    If someone would be kind enough to help me out with this problem, that would be great. Please let me know if I can provide any further information.

    Regards,
    Louise

  • Have you:

    1. installed or updated any plugins recently?
    2. activated a new theme?
    3. updated your existing theme?
    4. tried activating the default theme?

    Hi Esmi,

    The answer to all of those questions is no. I haven’t made one change on any themes / plugins etc for months.

    The site currently uses the wordpress default theme anyway.

    Should I install a new theme?

    Thanks

    Can you activate the default theme? I could have sworn I managed to get to the front page of your site a few minutes ago.

    Hi esmi,

    I de-activated the theme, and then re-activated it… I can see the front page however there is still the one error message at the top:

    Warning: Invalid argument supplied for foreach() in /home/measuredrecords/wordpress/wp-includes/classes.php on line 92

    Thanks for your help in this matter, its much appreciated

    Switch to the default theme, deactivate all plugins and let’s see what happens…

    Hi all,
    I managed to get the site back up by upgrading my wordpress version. Hope this helps anyone in the future.
    Cheers.
