I've been asked to remove some Malware from a friend's site.
I've found some wonky links in the
wp_postmeta table, but the
post_id that the field is associated with doesn't exist - and, weirdly, it's way too high. I think the fields have the
meta_key that starts with
What is the easiest way to search the
meta_value on those fields (seems to be JSON?) and delete the bad ones?
I found this post that suggested:
DELETE * FROM wp_postmeta WHERE post_id NOT IN (SELECT ID FROM wp_posts)
But when I ran (with updated table names) I got 0 results, which I feel shouldn't happen?
SELECT * FROM wp_postmeta WHERE post_id NOT IN (SELECT ID FROM wp_posts)
