How to hide complex error messages in the web UI for non-administrative users.
Hiding detailed error messages from users
When FotoWeb encounters an error it can deliver a detailed error message through the user interface. Such an error dump can contain a lot of information that may be more confusing than helpful to a non-administrative user on the system. You can disable such error details for users that are not site administrators by going into the site configuration and navigating to Settings - Behavior - Authentication. Simply tick Hide detailed error descrtiptions for non-administrative users.
Users will still receive an error message if something goes wrong, but it will not include all the details that may be more useful to a system admin.
