Disbaling browser archiving triggering directly in config.ini.file (no replies)

Hello,

I want to disable Archiving triggerering directly in config.ini.file and perform archiving by a cron, so i added the following lines in config.ini.php, in "[General]" section :

enable_browser_archiving_triggering = 0
time_before_today_archive_considered_outdated = 3600

But this settings do not seem to be used, as if i go to Admin panel> General Preferences in Piwik UI , I still get the following values :
Allow Piwik archiving to trigger when reports are viewed from the browser = Yes
Reports for today (or any other Date Range including today) will be processed at most every = 10

Is it normal ? The problem is that I want to do these changes directly in config files and not in the UI. Do I have to change these settings directly in DB ?

Thanks in advance !

David
