Hello,

by trying to install MySQL tables, following messages appears:

Deprecated: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in /customers/3/7/6/domain.net/httpd.www/t4/install/include/database.php on line 30 Warning: Cannot modify header information - headers already sent by (output started at /customers/3/7/6/domain.net/httpd.www/t4/install/include/database.php:30) in /customers/3/7/6/domain.net/httpd.www/t4/install/process.php on line 132

Even though I configured MySQLi, it allways tries to connect to DB via mysql_connect()
