Hi had an issue on my site earlier – unrelated to this – but whilst looking through error log i found millions of these
[11-Mar-2016 08:14:03 UTC] PHP Warning: Cannot modify header information – headers already sent by (output started at /home/eastmidl/public_html/mag/wp-includes/functions.php:3464) in /home/eastmidl/public_html/mag/wp-includes/functions.php on line 3503

the line in question is
header( ‘Content-Type: text/html; charset=utf-8’ );
The site is running fine – only thing it is doing is creating a larger error log file
any ideas
Hello,
This error refers to the WordPress files. The wp-includes folder is reserved for the core WP files. Please try to disable all your plugins and generate the error log again to see if there are no plugin conflicts. You can also try it with a wp default theme to rule out any theme setting or theme related bug (we have no reports of such errors with our themes). If the error persists, you may have to reinstall WP on your site.
Let us know how it goes.
Thank you!
