I just installed a new version of WP after moving databases and while that install was just fine, now there seems to be an issue with pluggable.php but not where I expected. This is the error I get when I try to activate or delete a plugin:
Warning: Cannot modify header information - headers already sent by (output started at /home/yoursite/public_html/wp-content/plugins/share-and-follow/share-widget.php:389) in /home/yoursite/public_html/wp-includes/pluggable.php on line 934
So what's at 934? This:
header("Location: $location", true, $status);
So how can I correct this beyond just killing the Share and Follow plugin?
