“an error occurred while accessing the database. Can’t find file: ‘./nm_scriptcase/sc_tbapl.frm’ (errno: 13) | Script: /var/www/scriptcase/devel/class/interface/nmTrashClean.class.php linha: 732”

Please help me!

export your projects, then re-install scriptcase so you will have the default user id / password again and then import the saved projects.

Thank you aducom, do you know if doing this i will need to configure Production environment again?

You talk SC login? or production enviroment login?
