Where does this script with messages in the portal come from?

[Community Alums]

There is a syntax error in a portal form. When I inspect the element it shows this script that contains these object messages and that is where the error comes from. Any idea where these messages can be modified to fix the syntax error? I searched for Widgets, UI script, UI macro and UI page and found nothing. An upgrade was recently performed on the instance, could the error come from there? thank you.

Hi! This is the error message.

Please check the "Widget options config" widget.

I checked that widget but it doesn't contain those object messages
