PHP Settings does not work properly for client

Panel does not update some php settings for client. For example, allow_url_fopen does not updated. I am using lastest Git Branch.

I installed i-mscp (selected php 5.6 with fcgid) from latest branch 1.6.x version from Github I logged as reseller and i created a client domain. When I want to change php "allow_url_fopen" settings of client, panel says that settings changed successfully. However, I can see that "allow_url_fopen" value did not changed in /var/www/fcgi/domain.com/php5.6/php.ini.
When I checked "allow_url_fopen" php value in the php_ini table, I see that the value also did not changed.

PHP: 5.6 with Fcgid

Per site selected, it is default option.
Creating a site with "allow_url_fopen = On" and changing of php settings does not work. As far as I can see, there are two table with related "allow url fopen option". One of them is in "domain" table, the other is "php_ini" table. I can see that there is no problem with "domain" table. All column fields are updated correctly. However, "allow_url_fopen" and "display_errors" column fields does not updated in "php_ini" table.
