hello! I'm in trouble by introducing PHP directive snippets on my websites, I'm using a server with debian jessie 8, apache and MariaDB, did the installation with the tutorial in ispconfig documentation. add new directive snippets on each website, but even after clicking resync and restart the server, the rules are not working. checked in the /var/www/conf/web1/, the php.ini file exists, and that the rules have been added in the last line of the file, but the original rules were not changed. what is the problem?
