No, you'll only have to clear the INI caches. This has nothing to do with Apache. Fire up the administration interface and click the "Clear INI caches" button. You can also run the clear cache script:
here site.ini.
i've tried to put setting on site.ini.append.php too but nothing to be appear.

# page itself while popup will create a new popup window with the debug.
# Popup window might not work in all browsers.
# Use either disabled, inline or popup
