Well, I think I got it all figured out.
While I was expecting the changes to take effect immediately, it seems there's a cache defined in user_ini.cache_ttl (300 in my case) in seconds.
After a change I made in the file, I had to leave the computer for a few minutes. After I got back, I saw the change took place. That's when I figured out there must be a cache issue and found this setting.
So, I think the wiki (
http://wiki.centos-webpanel.com/php-ini-per-folder) has to be updated with the following:
A. Newer versions of CWP are now using .user.ini instead of php.ini (by the way, Wordfence is using .user.ini as well).
B. You'll have to wait the amount of seconds mentioned in
user_ini.cache_ttl for the change to take effect.[/size][/size]Thank you all.
