BuddyPress

I install Buddypress on latest WP, and in the BuddyPress Component Setup I select enable groups, and not appear the button
…. I don’t know what can I do?, please!!!! HELP!!!!

Assuming you’re using the default theme, or a child theme, the easiest way is to go the “Groups” page (http://example.com/groups/). There is a button to “Create group” in the top-right area of the page.

With the default theme, the tab Groups appear, but when I click it, say:
‘Page Not Found
The page you were looking for was not found.’
and I want how to solve it? please!!!
