I'm getting an error when trying to upload a PDF file in version 2.1.2 -- I'm using the Manage/Posts tab, just below the post box... Upload button
The uploaded file could not be moved to /home/postpo5/public_html/postpositive/wp-content/uploads. Warning: Cannot modify header information - headers already sent by (output started at /home/postpo5/public_html/postpositive/wp-admin/admin-functions.php:1879) in /home/postpo5/public_html/postpositive/wp-includes/functions.php on line 1219
Here is line 1219 in finctions.php:
header('Content-Type: text/html; charset=utf-8');
I closed out of everything and tried again - no luck.
I understand that the headers cannot be modified once an upload is initiated, by what is outputing header info before attempting to upload?
