Then you need to check the `sys_objects_score` table with the query like:

SELECT `name`, `is_on` FROM `sys_objects_score` WHERE `name`='bx_timeline';

if the `is_on` value is 0 then you need to change it to 1 with this query:

UPDATE `sys_objects_score` SET `is_on` = '1' WHERE `name`='bx_timeline' LIMIT 1;

then clear the cache and check this part again.
