mac user needs help hunting down Headers already sent problem

  • i am getting this error-
    Warning: Cannot modify header information – headers already sent by (output started at /home/juice/public_html/wp-content/themes/revolution_magazine-20/header.php:4) in /home/juice/public_html/wp-includes/pluggable.php on line 390

    the error occurs in the sidebar but the offending file is index.php- the same sidebar seems to work fine on the homepage.php

    there is nothing ahead of <?php in any of the involve php files
    see for details

    as a Mac User, i cannot hold down the delete key for 15 seconds without deleting a good portion of the file because the delete key deletes to the left of the cursor.

    If i use textmate- https://macromates.com/ (a unix based text editor used by scripters)- and ask show invisibles- i can’t see any characters or spaces after or before.

    the pictures seen at https://madbadcat.org/wp/error_header/ are of the files opened in textmate so i am unsure as to how to proceed from here.

    i tried replacing pluggable with the one that came in the orignal wp zip
    i have made sure that transmit is uploading all the files as ascii; i am sasving the files utf8 seemed the best choice since textmate offers that or utf16 big endian or iso-58859-1
    no go.

    the error message started with all-in-one-seo but i deactivated it and the problem became translated to

    if understand what “header.php:4” means, its line 4 in the header… and this is line 4:

    Code:
    <meta http-equiv=”Content-Type” content=”<?php bloginfo(‘html_type’); ?>; charset=<?php bloginfo(‘charset’);?>” />

    i tried deleting that and the error became header.php:7

    the original problem started when i had the all-in-1-seo plugin installed
    i tried deactivating all-in-one-seo plugin and that gives me the error in the header.php as specified above.

    if i turn all-in-one-seo back on, it tell me its line 166
    which looks like this

    so its something about how the title is rendered.

    i realize you guys aren’t answering me cause you may think i didn’t do a search but i did, and i have read the FAQ and most of the problems other people have had have been with the wp-config. i went to the developer site for all-in-one but i suspect he is not supporting the plugin anymore because many people there are complaining about the same thing.

    i cannot find a solution anywhere on the web and i am at a loss as to how to fix this…

    If you are sure that is the starting point of your trouble, have you deactivated all plugins, made your .htaccess temporarily writable by WordPress and reset/updated your permalink structure and observed the result as a diagnostic step?

    On the downside, here are 697 forum hits on your search string.

    I had this problem earlier in a plugin. The fix is to remove all whitespace(blank lines) after the ?>

    It’s a common problem.

    Use a decent editor to sort it.

    i don’t know how to reset the permalink structure without screwing everything up and i am pretty much at a loss …

    i have followed the directions and suggestion in many of the pages that search string pulls up

    there are no spaces before <? or after the ?> in the plugin, header.php, functions.php, index.php, footer.php, or sidebar.php as far as i can see from within textmate as seen in the jpgs i posted at https://madbadcat.org/wp/error_header/

    if mac is leaving artifacts even textmate then i am just screwed…

    the most intersting part about it is that this only happens on the post pages- not the homepage which use the same sidebar.php
