Photoshop Script rename and export Artboard to PNG

@André35017048q0of 

Save for Web (Legacy) includes all visible artboards in the export, it doesn't save each artboard individually unless you isolate the visibility to the active artboard. Save for Web (Legacy) pre-dates Artboards, so we are lucky that it works as expected! :]

I also note that the script is renaming the artboards in the layers panel, is this what you want? I would expect the script to only name the output files, leaving the artboards named as they were.

EDIT: Perhaps something like this (I have also set the Title field to be active by default) –
