My method :

First of all, you must ensure you are able to execute SQL queries. For that, open /include/config.php file, and enter your userid in line :

PHP Code:

$config['SpecialUsers']['canrunqueries'] = '1'; 


Second, go to your AdminCP -> Maintenance -> Execute SQL Query

Execute theses 2 queries in Manual Query box (one by one) :

PHP Code:

UPDATE user SET dbtech_vbactivity_autocollapse_stats = '1' 


and

PHP Code:

UPDATE user SET dbtech_vbactivity_autocollapse_bar = '1' 


All your users will be affected by theses queries.

Lex :

1 = collapsed
0 = expanded
-1 = vBulletin default setting
