Need Help With Blog Installation Error

by MMcJunkin
5 replies
I have uploaded all my files for a ready made blog, but I am getting the following error when trying to access the site or the wp-admin.

Warning: Cannot modify header information - headers already sent by (output started at /home/digiinfo/public_html/forexsite/blog/wp-settings.php:723) in /home/digiinfo/public_html/forexsite/blog/wp-includes/pluggable.php on line 865

Can anyone tell me what the problem is or help me fix it.

Most obliged!

Warmly,
Mellisa McJunkin

    Hi Mellisa,

    It'll be one of your plugins that's causing that error message (for me, it was the NextGen Gallery plugin - may be different in your case, but if you're running that plugin that's the first place I'd look).

    If you're able to access the Wordpress Adminstration area, go to Plugins and disable them one by one until the error disappears, to isolate which plugin's causing the issue.

    If you're unable to access the Wordpress Administration area, use your web host's file manager or FTP client to access the wp-content/plugins folder, removing each plugin folder one by one until the error disappears, to isolate which plugin's causing the issue.

        Well, I just did try that. Removed each plug in through my Cpanel and reloaded each time and I still get the same error message.
        Do you, or anyone else have any other ideas?
        Thanks again!

      Hi Melissa,

      What's happening is that the file pluggable.php is attempting to send the command
      header("Location: $location") - which is on line 865 of that file.

      The file wp-settings.php on line 723 has already sent something to the browser and when the above header command is sent. PHP says - hang on you can't do that you've already begun sending stuff...

      Now I'm running wordpress 2.8.4 and my wp-settings.php file isn't even 723 lines long.
      I'm not sure how long this file is on other versions. It could be that this has been "added" to.

      The short version, without knowing anything else apart from the error messages, is that something on line 723 of your wp-settings.php file has performed some kind of output.

      "Sometimes" spaces or newlines can sneak into a file when you are looking at it, making changes etc and cause this problem.

      And as can happen on occassion the error reported can be a clue and not the actual place it's occurring.

      If you let someone have a look at the file(s) they should be able to pick it up pretty quickly.

      At this point in time, it's about all I can offer on the matter which doesn't help you a great deal.

      Cheers
      Another Tim
