How can I use BuddyPress with my existing WordPress theme?
BuddyPress is designed to work out of the box with its bundled default theme. The easiest way to run BuddyPress will always be with this theme, a child theme, or a purposely built BuddyPress theme. However, it’s actually very possible to use BuddyPress with any existing WordPress theme.
To enable your existing WordPress theme for BuddyPress, please download and activate the Buddypress Template Pack plugin. This will run you through the process step-by-step.
