When editing old posts or adding new ones, I get the following error message:
Warning: Cannot modify header information - headers already sent by (output started at /home/miryna/public_html/bardbulletin.com/wp-content/themes/bulletin/functions.php:13) in /home/miryna/public_html/bardbulletin.com/wp-includes/classes.php on line 1571
Any ideas what is causing this? The message appears as soon as I click in the editing text area.
My site is here, if it helps.
Edit: Wonderful, now the same message appears when visiting the front page.
