Warning Invalid Argument Supplied/ Cannot Modify Header

  • I’m directed to a page with about 7 lines of warnings about headers already sent by (/……..wp-admin/includes/plugin.php:1395) in /home/content/46/7608346/html/maketingsite/wp-cotent/plugins/nextgen-downloadgallery/includes/class.NextGENDownloadGallery.php on line 399.

    It says this for line 399-406 then it has a bunch of foreign symbols like squares and dashes and even alphabets.

    What could be the problem. I have NextCellent gallery installed but deactivated.

    The weird thing is that it’s doing it a windows machine using chrome. I’m using a Mac and chrome and it works fine. However, when I use it on Safari I get the same error. And when my coworker tries to use it on explorer same result.

    So far the download only seems to work in Chrome on a Mac.

    Please help!!!!

    G’day SocialLabor,

    That means a plugin or your theme is sending something to the browser too soon (quite likely an error message). Please post a link to your website so that I can look at the browser output.

    cheers,

    Thanks Ross again for the reply. Glad to know you are ok.

    I took the feature down from the menu so that it is not accessible. However you can still access with the direct url

    /content-networking

    I hope you guys stay safe and that things get back to normal soon. Looking forward to your response.
