ERROR: Cookies are blocked due to unexpected output.

  • I have looked over other threads with this same problem. Unfortunately none have worked to fix my problem. Here is what I have tried:

    The site works for viewers, but try to login and you get that error.

    /wp-admin shows the white screen of death. /wp-login.php will show me the above error (cookies are blocked due to unexpected output).

    advanced-cahce.php from the plugin QickCache was throwing header already sent error, but I deleted the offending issues and it stopped showing a php error in Debug mode.

    So now it still throws the error, with no php issues.

    the UTF is UTF-8 (checked and confirmed, so no issues there)… I use Sublime PHP as my editor of choice.

    The site was moved from one server to another.

    I did disable all of the plugins via the database… but I still get the error.

    The site is 317sounddesign.com

    So… any help is appreciated.

    Thank you.

    Brad

  • This is a tricky problem, maybe this will help:

    On one occasion I had this because a file in my theme had an extra newline at the end of the last line. This emits the newline into the result being assembled, and locks off using cookies etc as the header has been started. So look for these invisible newlines.

    Unfortunately I have looked and that doesn’t fix it. I have never run into this problem.

    I have a second site that I just transferred that doesn’t have any cache program and I am still running into the same issue. This time WordPress Debug shows no issues.

    So I am at a complete loss.

    Do these two sites use the same theme ?
    Do they use the same plugins ?
    Disable any that they share (or change theme) and try and isolate what they share which is causing this.
