  • After upgrading to WP 3.8, I noticed that a public the page with [catlist] shortcode displayed an error message:

    Warning: Cannot modify header information – headers already sent by (output started at /home/invivoan/public_html/wp-content/themes/simplebusiness_v1_1/header.php:2) in /home/invivoan/public_html/wp-includes/pluggable.php on line 896

    In case the problem was with the theme, I loaded the new Twenty Fourteen theme and the error message is:

    Warning: Cannot modify header information – headers already sent by (output started at /home/invivoan/public_html/wp-content/themes/twentyfourteen/header.php:13) in /home/invivoan/public_html/wp-includes/pluggable.php on line 896

    When I take away the sections with the [catlist] shortcode, the page loads.

    Yet somehow, the page with [catlist] loaded fine if logged in as admin. In case it matters, site access is controlled uses the Member Access plugin Version 1.1.6 by Chris Abernethy.

    This is really strange, did you try disabling all of the plugins and enabling them one by one to see which one is the cause of this error? I wasn’t able to reproduce the bug on my side, if any other user is having this issue please report it here.
