BuddyPress.org

Hello guys, I hope that you are well. I run WP 3.8 Multisite, subfolders on shared server. WP installed in root (example.com). There are no users except for super admin user. The site is new with no blog posts or pages, except for sample page and sample blog post (Hello World!)

1. I have FTP buddypress folder and installed buddypress on a secondary blog example.com/site2, as described in link below

2. I have made the changes to wp-config.php only

3. I have configured pages for example.com/site2, except for Activate, site tracking and Register pages.

4. I have checked phpmyadmin, all BP tables are there.

5. I went to log out the website and I got a nice “Access forbidden” blank page.

6. I have started panicking so I have deleted buddypress folder from server via FTP.

7. I have found out that the error was one instruction in the .htaccess

8. I have uploaded buddpress via FTP and activated the plugin network wide.

Question, do you suggest me to start using buddypress plugin or shall I follow the instructions below to ensure a clean plugin installation?
