After I uploaded a new Plesk license with PostgreSQL, I have been trying to setup a database administrator's Credentials. However, Plesk doesn't let me create a login and password. I received the following messages: "Unable to update database parameters: Unable to change database login: Unable to change administrator's login: Error while execute pg-manager: Unable to start PostgreSQL.1" I use Plesk vesion 7.5.2 for FreeBSD4.9 that come with Postgresql-server-7.4.6. Can anybody guide me how to fix the problem? Thank you very much.
