WordPress Database Reset All Users' Metabox Locations

wp-db-reset-users-metabox-locations.sql

-- Reset all users' metabox placement. This is useful when changing location of existing ACF field groups.
-- Run these separately, and replace the table prefix and meta_keys with your own. 
-- Search for current metabox values:
SELECT *
FROM wp_usermeta
WHERE meta_key 
LIKE 'meta%'

-- Look for the meta-box-order_[post_type_slug] and metaboxhidden_[post_type_slug] keys.
-- Run the reset on the necessary rows based on the post type you are targeting.
UPDATE wp_usermeta
SET meta_value='a:0:{}'
WHERE meta_key IN ('meta-box-order_[post_type_slug]','metaboxhidden_[post_type_slug]')
