I've had relationships set up in several places on this site for over a year.
No edits have been made.
They stopped working after the last MetaBox Update.
Before (taken from a staging site from a backup):
https://www.awesomescreenshot.com/image/42863203?key=513286e2f3e32af891c0e67018cb85c9
Now, it returns this error on the front-end:
WordPress database error: [Unknown column 'mbr_order' in 'order clause']
SELECT wp_dgs8sn_posts.ID FROM wp_dgs8sn_posts INNER JOIN wp_dgs8sn_mb_relationships AS mbr ON (mbr.type = 'instructors-to-units' AND ((mbr.from = wp_dgs8sn_posts.ID AND mbr.to IN (5512)) OR (mbr.to = wp_dgs8sn_posts.ID AND mbr.from IN (5512)))) WHERE 1=1 AND ((wp_dgs8sn_posts.post_type = 'course_unit' AND (wp_dgs8sn_posts.post_status = 'publish' OR wp_dgs8sn_posts.post_status = 'private'))) GROUP BY mbr_from, mbr_to, wp_dgs8sn_posts.ID ORDER BY mbr_order
ASC, mbr_id DESC

This is true of all relationships across the site.
Things on the backend appear fine.
Thank you.
