I get the following error when publishing a new post or when publishing after editing a post:
Warning: Cannot modify header information - headers already sent by (output started at /home/httpd/vhosts/myserver.com/httpdocs/wp-inst/wp-includes/comment-functions.php:516) in /home/httpd/vhosts/myserver.com/httpdocs/wp-inst/wp-admin/post.php on line 118
The post does get published/edited, but this error page is received. I then have to click the browser back button to get back in admin again.
How can this be remedied?
