Hi,

From debugging mode debug.log:

[24-Aug-2021 15:31:44 UTC] WordPress database error The SELECT would examine more than MAX_JOIN_SIZE rows; check your WHERE and use SET SQL_BIG_SELECTS=1 or SET MAX_JOIN_SIZE=# if the SELECT is okay for query SELECT SQL_CALC_FOUND_ROWS tU.*, COUNT(tS.id) as cnt_mails FROM www0_bft_users tU
				LEFT JOIN www0_bft_sentmails tS ON tS.user_id=tU.id 
				WHERE 1 
				GROUP BY tU.id ORDER BY email ASC LIMIT 0, 20 made by do_action('arigato-light_page_bft_list'), WP_Hook->do_action, WP_Hook->apply_filters, bft_list

Thankfully I seem to have 487 rows of 25 users in bft_users table in phpmyadmin

Where have they gone in the WordPress admin?

One of your updates must have caused this???
