Just did a setup of a new ispconfig on an external server (latest isponcif 3 on debian 6) I must have done something wrong with changing the password for admin. I've lost the 'system' tab. This means that I can't change any system settings anymore. Can I get this back from the database ?
Login to phpmyadmin, go to the dbispconfig database and there edit the user admin in the sys_user table. Set the value of the "modules" field to Code: dashboard,admin,client,mail,monitor,sites,dns,vm,tools,help
