Your recommendations were already in place (see images), but still no display for the custom HTML substitution (2nd Group column).
The list is filtered by these same plans:
( ( SELECT COUNT(*) FROM `#__cbsubs_subscriptions` AS sub WHERE sub.`user_id` = u.`id` AND sub.`plan_id` IN ( 24, 25, 27 ) AND sub.`status` = 'A' ) >= 1 )
and the proper count is listed at the top of the list.
The plan image displays are working, and whether it should or not allow it, search can be set and is enabled. That's why it threw me, because the custom HTML type, for example, doesn't even have the search field available to set.
Anything else I could be missing?
