When an error is found, the required field is highlighted and the cursor is placed there. Tips without user criticism. The text of the error states the possible cause and the following actions (if the user cannot correct the error) for example: "We are updating the server. Try in 2 hours" Error pages 404 and 503 tell the user what to do next. The use of an exclamation mark (!) in errors is avoided. All errors are written in the same style and Tone of Voice.
