Entered a post but did not see the expected screen. Instead a white screen with this:
Pingbacks were closed this one time to stop pingback and trackback spam. To reopen go to Settings >> Spam Free WordPress
Warning: Cannot modify header information - headers already sent by (output started at /home/drum/public_html/wp-content/plugins/spam-free-wordpress/tl-spam-free-wordpress.php:130) in /home/drum/public_html/wp-includes/pluggable.php on line 881
Pingbacks and trackbacks were ON in your settings section. I have no clue what the second error is. Had to turn the plugin off so this error screen would not confuse editors. DO you have a more polite way of alerting? Doesn't appear that settings was actually checked.
