Illegas string offser

Could you please check which of these posts have “Exclude this post” ticked – you’ll need to edit the posts and check the Top 10 meta box.

And then resave the post to see if it works.

Another thing to try is to edit the Top 10 file

https://github.com/WebberZone/top-10/blob/v2.7.0/includes/modules/exclusions.php#L24

$meta_value = (array) maybe_unserialize( $tptn_post_meta['meta_value'] );
