 * 
 * Find the line of code >> define( ‘WP_DEBUG’, false ); << and replace it with the 3 lines of code below. 
 * You must set WP_DEBUG to “true” to enable the display of notices during development. 
 * WP_DEBUG_DISPLAY should always be “false”, unless you have a very strong reason to change its value to “true”. 
 * You should have a debug.log file in WordPress, if not, you must create it and set WP_DEBUG_LOG to “true”. 
 * It is strongly recommended that plugin and theme developers use WP_DEBUG in their development environments, with caution.

Based on crashutah, apeatling https://wordpress.org/plugins/bp-disable-activation/ Disables the activation email and automatically activates new users in BuddyPress under a standard WP install and WPMU (multisite). Also, automatically logs in the new user since the account is already active.
Basically i updated the plugin and added some features like:
-Option to turn off automatic login 
-Redirect options after account creation
Known Bugs: 
-Doesn’t do the automatic login if you allow blog creation during the user creation in WPMU (multisite)
