Uncaught TypeError: Cannot read properties of undefined

Hello,
I have a problem with the “Chronogolf” plugin. It should appear on the Croatian and English versions of the website, but it only appears on the English version. I checked the console for any errors and encountered the problem Uncaught TypeError: Cannot read properties of undefined (reading ‘toLowerCase’) and I think that’s the problem why the widget is not displaying.

Does anyone know how to fix this problem?

Regards,
Mateo
