I am doing a multi server setup using Ubuntu 16.04 and mariadb from the perfect server tutorial. This is not the first time I've done this, just the first time in awhile. BTW love the new look of the web interface. When trying to run the expert install for my nameservers I get the following error. PHP Fatal error: Uncaught Error: Call to undefined function mb_detect_encoding() in /tmp/ispconfig3-stable-3.1-b218ba46f301ea7b5596639180782c4e00c6f1f2/install/lib/mysql.lib.php:445 Stack trace: #0 /tmp/ispconfig3-stable-3.1-b218ba46f301ea7b5596639180782c4e00c6f1f2/install/lib/mysql.lib.php(146): db->escape('dbispconfig') #1 /tmp/ispconfig3-stable-3.1-b218ba46f301ea7b5596639180782c4e00c6f1f2/install/lib/mysql.lib.php(228): db->_build_query_string('CREATE DATABASE...', 'dbispconfig', 'utf8') #2 /tmp/ispconfig3-stable-3.1-b218ba46f301ea7b5596639180782c4e00c6f1f2/install/lib/mysql.lib.php(267): db->_query('CREATE DATABASE...', 'dbispconfig', 'utf8') #3 /tmp/ispconfig3-stable-3.1-b218ba46f301ea7b5596639180782c4e00c6f1f2/install/lib/installer_base.lib.php(232): db->query('CREATE DATABASE...', 'dbispconfig', 'utf8') #4 /tmp/ispconfig3-stable-3.1-b218ba46f301ea7b5596639180782c4e00c6f1f2/install/install.php(590): installer_base->configure_database() #5 {main} thrown in /tmp/ispconfig3-stable-3.1-b218ba46f301ea7b5596639180782c4e00c6f1f2/install/lib/mysql.lib.php on line 445
