Hi ! I recently update my ISPConfig installation from 220.127.116.11 to 18.104.22.168 and it worked fine except for one point. I found that association between users databases and databases is now 1:n while it was 1:1 before. It seems to be logical. But my problem is that new database users created in ISPConfig are not transmitted in MySQL server. Here is the log of ISPConfig (DEBUG level) when I try to create a database user : Code: [[email protected] The credentials in /usr/local/ispconfig/server/lib/mysql_clientdb.conf are correct. When I try to create a database from ISPConfig it works. When I try to create a database user from phpMyAdmin it works. When I update an existing datable user from ISPConfig it works ! Where should I look for to solve the problem ? Thanks !!
