QTX menu bad link do white page

Hi,

I’m using the menu option to diaplay QTX langueges available on menu > submenu.
But the url of the language missing a / at the end.

ex : https://www.mywebsite.com/en
instead : https://www.mywebsite.com/en/

And so for all language… any language select make a white page. Is it a settings to correct that ?

Thanks for your help,
Mike
