Hello all, I know this is a noob question but, in fact this is my first personal server. I've tried to restore a ispconfig_db_backup using the method https://www.howtoforge.com/faq/6_4_en.html: Code: mysql -h localhost -u root -p dbispconfig < '/root/ispconfig_db_backup_2015-04-26_20-46.sql' But I've returned the error: Code: ERROR 1062 (23000) at line 51: Duplicate entry '1' for key 'PRIMARY' This mean already exist something so it not rewrite on it, right? Then i Tried to Drop the "dbispconfig" Database but when I retry with the command, it doesn't found the tables... I've had some problem upgrading from wheezy to jessie Debian, so I reinstall all servers needed, re-following the "Perfect Server Guide" and deleting only the "dbispconfig" database and the /user/local/ispconfig folder. So infos of the websites should be still there. I have made a backup before reinstalling by command "php -q update.php". Hope some kind soul can help me! Thanks for Your Attention, Have a Nice Day.
