BuddyPress.org

You will need to change the HTML structure in the BuddyPress templates that you copied into your theme to match the structure in your page.php or index.php file.

There are two methods for making the necessary template changes.

The first method is to locate the following templates (leave out any folders that you didn’t copy over in Step Two):
/activity/index.php
/blogs/index.php
/forums/index.php
/groups/index.php
/groups/create.php
/groups/single/home.php
/groups/single/plugins.php
/members/index.php
/members/single/home.php
/members/single/plugins.php
/members/single/settings/delete-account.php
/members/single/settings/notifications.php
/members/single/settings/general.php
/registration/register.php
/registration/activate.php
Alternatively, you may find it easier to make copies of your theme’s header.php, sidebar.php and footer.php and rename them to header-buddypress.php, sidebar-buddypress.php, and footer-buddypress.php.

Then you can alter the structure of these new template files (header-buddypress.php, sidebar-buddypress.php, and footer-buddypress.php) to resemble your theme’s page.php (or index.php).

Once you are done matching up the HTML structure of your theme in these template files, please take another look through your site. You should find that BuddyPress pages now fit inside the content structure of your theme.

Finishing Up

You’re now all done with the conversion process. Your WordPress theme will now happily provide BuddyPress compatibility support. Once you hit the finish button you will be presented with a new permanent theme options page, which will allow you to tweak some settings.
