For original script:

1. It will not allow to add personal address with / in it.
2. Script checking for path to be not in the pages of website (listing i think is page path)


This configuration is for Personal Address field and not for Username field originally, but as we changed this logic for your website i'm not sure how it will work.
If you dont want / to be in the username and path please check it on your website and if not working let me know (ticket better)
