When I uploaded wordpress seo it asked me to track my website at the top of the page. When I said yes, it gave me this WARNING text
Warning: Cannot modify header information - headers already sent by (output started at /home/fbdoc/public_html/everythingswimmingpools.com/wp-admin/includes/template.php:1642) in /home/fbdoc/public_html/everythingswimmingpools.com/wp-includes/pluggable.php on line 876
Is this a problem?? I am a seo rookie and do not want to start off on the wrong track.
Any help is very much appreciated and Thanks in advance.
