Warning: Cannot modify header information - headers already sent by in wordpress (3 posts)

    For one of the pages, I am getting the following: "Warning: Cannot modify header information - headers already sent..." but its not involving the wp-config file instead to do with the wp-includes/pluggable.php.

    I have read other entries that have had a similar problem of which it suggests to remove any white space before and after the <?php and ?> tag.
    I have done this and uploaded but the problem still appears.

    Any suggestions on how this can be solved will be much appriciated

    Could be a Plugin, or theme code conflict.

    1. Disable your Plugins, and revert your theme to the default Twenty Ten.
    2. Do you still get the error?
    3. If no then switch your theme back. Get the error now?
    4. If no then it is not your theme but a Plugin.
    5. Switch on your Plugins one by one to see which one is causing the problem.

    I am still getting the same error. I have followed your steps and it hasn't worked.

    the line it keeps refering to in the code is "header("Location: $location");"

    I am not sure how this is a problem and how to fix this problem
