In aggregated query without GROUP BY, expression #1 of SELECT list contains nonaggregated column 'ulagym_db.fl_listing_plans.ID'; this is incompatible with sql_mode=only_full_group_by
Query:
SELECT *, COUNT(*) AS `count`, SUM(IF(`Sticky` = '1' OR FIND_IN_SET('218', `Category_ID`) > 0 , 1, 0)) AS `match_count`, SUM(IF(`Price` > 0, 0, 1)) AS `free` FROM `fl_listing_plans` WHERE `Status` = 'active' AND `Type` != 'featured' LIMIT 1
