Help for Buddypress?

The reason I am requesting help here is because I am not getting help in the Buddypress forums. I seem to be having a problem with the Buddypress urls. I want to create a new group, but when I click on the link it takes me to a blank page.
My problem is: when I click on the link “Add New” it takes me to a page with nothing on it but the title “archive”. And if I try accessing the page https://www.thebrazilianlanguage.com/wordpress/groups/create/
I get an error 404 page not found.
