BuddyPress.org

You did follow this:

https://codex.buddypress.org/getting-started/installing-buddypres

and do have the member them in the correct place?

where it says:

6. The plugins are now activated and running, but you will need to move the themes to the correct locations. Move /wp-content/plugins/buddypress/bp-themes/ to /wp-content/bp-themes/

7. You can use any WordPress theme as your root blog theme, but BuddyPress comes bundled with an extra “home” theme that you can optionally use. To install it, move /wp-content/bp-themes/bphome/ to /wp-content/themes/bphome/.

you will then need to edit the member theme to reflect similar changes in the base theme.

Hope that helps.
