 * Hello everyone –
    I’m new here. Please help!!
 * I have an issue that I’m battling for the last 2 hours with no luck.
    I’m getting
   an error message when I go to my blog admin:
 * `Warning: Cannot modify header information - headers already sent by (output 
   started at /home/content/48/7360348/html/manyerot/wp-content/themes/twentyten/
   functions.php:1) in /home/content/48/7360348/html/manyerot/wp-includes/pluggable.
   php on line 934`
 * I have deleted all unseen spaces at the line mentioned and at the end of the 
   document. I have reverted to the original file that I downloaded in the installation
   yet I still get this error message.
 * Please help, I don’t know what else to do.
 * Thanks,
