Is there a way to prevent the red exclamation mark?

Hi,

I have a question regarding the red exclamation mark that shows up when some errors(such as validation, or system errors like null pointer) occur.

Now, while this is fine to display during development/debugging phase, it is not needed for customer facing sites in production. User's don't need to see the entire stack trace :grin: It creates a bad experience.

How to hide it or prevent its display in production system?

Thanks
