Re: cannot enable multisite after buddypress install
If you have BP installed already, and you want to enable multisite https://codex.wordpress.org/Create_A_Network :
1. You need to deactivate all WP/BP plugins and change to default theme (twentyten) first.
2. Note, that if you have had single WP for some time, you can only go multisite in subdomain structure i.e. http://newsite1.example.com. Make sure that your server is set up for that.

3. You only add `define(‘WP_ALLOW_MULTISITE’, true);` to wp-config.php to get `Tools > Network` in your dashboard to start the process. If your server is up to the task, follow dashboard message to enable multisite in your install.

= If you encounter multisite creation problems, resolve that first in WP forums https://wordpress.org/support/forum/multisite before re-activating BP/WP plugins.
