Successful Disabling
Hello!
You should folow steps below:
Open phpMyAdmin (your wp DB) -> SQL and run:
Code:
UPDATE wp_posts SET ping_status='closed' WHERE post_status = 'publish' AND post_type = 'post';
UPDATE wp_posts SET ping_status='closed' WHERE post_status = 'publish' AND post_type = 'page';
Don't forget to back-up your database before running this. This will close all pingbacks for posts/pages added until now.
Go to Discussion Settings and disable Allow link notifications from other blogs (pingbacks and trackbacks.)â€
Go to Comments and search "[...]" (without quotes). It will show a list of all trackbacks. You should delete them (Be careful: if one of real comments contains [...] within, then it will be shown here). You can delete them (Trash & Empty Trash).
Hope this helps!
