Currently my users cant login with ftp. Mysql and ftp are running. if i check mysql.conf from pure-ftpd user credentials are fine. so i try to connect on cli with mysql -u ispconfig and password from mysql.conf. I can connect. if i take a look in syslog i found this: [ERROR] The SQL server seems to be down [Access denied for user 'ispconfig'@'127.0.0.1' (using password: YES)] whats wrong?
