Warning: mysql_pconnect(): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111) in /var/www/html/classes/DBController.class.php on line 18

Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/Helsinki' for 'EEST/3.0/DST' instead in /var/www/html/exceptions/DBException.class.php on line 50
