 * All I did was change my header on my theme and now when I try to update a post
   I get:
 * Welcome To Our Site
    Warning: Cannot modify header information – headers already
   sent by (output started at /home/consumer/public_html/wp-includes/post-template.
   php:54) in /home/consumer/public_html/wp-includes/pluggable.php on line 890
 * I presume I look for a blank at line 54 in post-template.php:54 or 890 in pluggable.
   php? I can’t see any blank or whitepace at the ends of those lines. Or should
   I be looking somewhere else.
