 * Firstly, I am having difficulty getting this to be fluid and to go past a 1028
   width. I am also getting an error on the /wp-admin/themes.php?page=custom-header
   page:
 * Warning: call_user_func_array() [function.call-user-func-array]: First argument
   is expected to be a valid callback, ” was given in /home/myacct/public_html/mywebsite.
   com/wp-includes/plugin.php on line 395
 * I don’t get it with the default theme installed.
 * Take Care, Sharon
