Ope!
Sorry about that, something was misconnected.
While you’re here, this is an example of how to address Jakob Nielsen’s Usability Heuristic #9 “Help users recognize, diagnose, and recover from errors.”
My personal preference for addressing errors is to:
Explain what went wrong in human language
Add some humor to account for part of the user’s frustration
End with a direct instruction to get the user on the right path again.
