I am experimenting with differnt plugins to notify users of new posts.
Mailing-List v4.0 beta in partucular is kicking back this error when I try and post entry with the "Add notification for this post in the newsletter " checked.
Warning: Invalid argument supplied for foreach() in /home/indimas9/public_html/wp/wp-content/plugins/mailing-list.php on line 647
Warning: Cannot modify header information - headers already sent by (output started at /home/indimas9/public_html/wp/wp-content/plugins/mailing-list.php:647) in /home/indimas9/public_html/wp/wp-includes/pluggable-functions.php on line 272
I got similar errors in the previous version of this plugin as well.
