“Cannot modify header information” error in 2.7

    Just started getting this error message since 2.7 update:

    Warning: Cannot modify header information – headers already sent by (output started at /home/username/public_html/wp-content/themes/responsive/core/includes/functions-admin.php:126) in /home/username/public_html/wp-includes/pluggable.php on line 1210

    I was able to fix it by commenting out the <style> section that seems to be incorrectly inserted in the “functions-admin.php” file like so (lines 108-126):

    ?><?php /*
<style>
.addon-count {
    display: inline-block;
    z-index: 26;
    margin: 1px 0 0 2px;
    margin-top: 1px;
    margin-left: 5px;
    padding: 0 6px;
    border-radius: 10px;
    color: #fff;
    background-color: #d54e21;
    font-size: 9px;
    font-weight: 600;
    line-height: 17px;
    vertical-align: top;
}
</style>
*/?><?php

  • I have admin errors everywhere I turn because of the same issue. This appears to be a major problem in the 2.7 update.

    I’m getting the exact same issue.

    @fssbob and @mcolli10, does the temporary “fix” I outlined in my post work for you as well? (It might help the developer address the issue more quickly if there’s confirmation of what caused the problem.)

    had the same problem, but my functions-admin.php looks somewhat different than yours, @liquidsunshine. I just installed v2.7.1

    In line 108-110 there are tags for ending end beginning a php-codeblock. So at least one blank line would have been printed. After removing them it worked again.

    before:

             * end of each line for what each argument will be.
         */
?>

<?php   
        $style = 'display: inline-block;z-index: 26;margin: 1px 0 0 5px;padding: 0 6px;border-radius: 10px; color: #fff;background-color: #d54e21;font-size: 9px;line-height: 17px;vertical-align: top;';

    after:

             * end of each line for what each argument will be.
         */

        $style = 'display: inline-block;z-index: 26;margin: 1px 0 0 5px;padding: 0 6px;border-radius: 10px; color: #fff;background-color: #d54e21;font-size: 9px;line-height: 17px;vertical-align: top;';

    @magenbrot – Yep, that’s what I saw when upgrading to 2.7.1 as well. It’s still broken, but removing the extra whitespace still fixes it. It’s a little concerning that two releases in a row have been broken this way… it reduces my faith in the theme devs.

    I agree. There is still a blank space between a closing PHP tag and an opening PHP tag at line #109 in version 2.7.1 for functions-admin.php. Those PHP tags don’t even need to be there since the change made from 2.7 to 2.7.1 now assigns the style code block to a PHP variable called $style as outlined by Magenbrot and liquidsunshine above.

    Same issue here.

    Deleting the blank line 109 from functions-admin.php seems to have fixed it. (If not, I’ll roll back to a previous version until the developer can get things right)
