If you’ve ever changed themes or plugins which use shortcodes you most probably will be left with unused shortcodes on your pages and posts.
Example: [table “style_35” not found /]
Rather than hunt them down manually, there’s a better solution to remove unused shortcodes quickly & easily.
Caution: Always create a full backup of your databases before executing database queries. You can do this be exporting a copy in PhpMyAdmin or downloading a copy from cPanel.
You’ll find PHPMyAdmin offers a field for databases queries.
Enter this code and simply replace the example shortcode with the text of the shortcode you want to remove.
UPDATE wp_post SET post_content = replace(post_content, '[example]', '' ) ;
