Could not update display


Could you please tell us what CMS and client version do you use?

so, "SQLSTATE[22003]: Numeric value out of range: 1416 Cannot get geometry object from data you send to the GEOMETRY field"

It might be related to outdated MySQL, so you could have a look at it.
Did you set latitude/longitude in display edit?

Perhaps have a look at this topic with similar issue for more details.
