      For anyone that can read this, i found my php.ini working in another path, was
      /etc/php/7.0/cgi/php.ini

      Another paths i used in the past were
      /etc/php/7.0/apache2/php.ini
      /etc/php5/apache2/php.ini

      Is there any command as
      php -i | grep php.ini
      that works for any Linux installation and not just CLI for looking for a file?

      I have Debian 9 and have changed the upload_max_filesize to 20M but still can’t upload a 4 megs file, an mp4, via WordPress installed in ISPConfig.

      It continues saying that the size of the file exceeds the allowed size of the site.

      I have changed the upload_max_filesize value in /etc/php/7.0/apache2/php.ini and also in /etc/php/7.0/cli/php.ini

      Any ideas of how it didn’t worked? Maybe there’s something i don’t realize right now.
