I am having an error like this :
Warning: Cannot modify header information - headers already sent by (output started at /home/zk2ba8xn663w/public_html/wp-includes/formatting.php:5100) in /home/zk2ba8xn663w/public_html/wp-includes/pluggable.php on line 1219
How should i approach to solve the problem as error shows the WordPress core files?
This is the line there :
if ( !$is_IIS && PHP_SAPI != 'cgi-fcgi' ) status_header($status); // This causes problems on IIS and some FastCGI setups header("Location: $location", true, $status); return true;
can if i use $location in my theme can it cause any problem? please help
