When a user indicates if a knowledge article was helpful or not a message is displayed: Thank you. How can you change this?

The 'Thank you' message is defined in two places. The platform uses a Macro: /nav_to.do?uri=sys_ui_macro.do?sys_id=d44e4272c33321000096dfdc64d3aea0. There are two messages you'd need to change.

The portal uses two Widgets: /sp_widget_list.do?sysparm_query=sys_idIN5f599c490be432004ce28ffe15673a5b,69a638365b722200a9ad09ed5a62bceb. Check the Server Script, you need to change it here.

Just to clarify, if anything changes in future releases, the Macro and Widgets will get skipped as part of the upgrade. Any effects from the change we will not support as it will be considered customisation.
