# Can't Login to Admin Panel!!

 * I recently updated to the latest version of wordpress, and now when I go to my
   domain this code is listed on top publically:
 * > Notice: get_theme_data is deprecated since version 3.4! Use wp_get_theme() 
   > instead. in /home/XXXXX/public_html/wp-includes/functions.php on line 2839
 * When I attempt to login, the following code is added below it:
 * > Warning: Cannot modify header information – headers already sent by (output
   > started at /home/XXXXX/public_html/wp-includes/functions.php:2839) in /home/
   > XXXXX/public_html/wp-includes/pluggable.php on line 680
 * I have downloaded an FTP client to try and fix these problems so that I can login
   normally again, however, I do not know what is broken. I have checked for space
   at the beginning of the wp-config.php, but there was none. Please help?
