I move my WP from a shared hosting to one VPS server. All work fine but the related posts in all posts are disappeared. I check all posts in the related posts field and all are empty. In that way I don’t have any related post.
I try to reactivate/reinstall, via WP or via FTP, delete YARPP folder etc. etc. but without success.
I moved my wordpress db and files from a windows host to a linux one, and everything is working normal but YARPP, just showing: no related posts.
I use a thumbnail tempelate.
I tried to change threshold, enble/disable, clear those tables but no change happened.
@farnood, no, I’m not sure. It seems those are the main culprits. You could check your PHP and SQL error logs (which you can get from your hosting) and see if there seem to be any YARPP-related errors there.
