I have added extra fields and categories, but they aren’t visible. What should I do?

New fields aren’t visible by default. You have to add these to your role: go to menu ManagementBase tabelsRoles and click on the role that links to these fields. Click on the¬†newly created options and click on Save. The roles still aren’t visible, because your authorization is determined before you login. Now logout and login to start a new session and the new fields will be available.
