@demetrius-pop rename the buddypress folder in wp-content/plugins to e.g. buddypress-xxx and then check if you can access wp-admin
– Was BuddyPress installed in main site or subsite?
– What plugins are you using? 
		
	 
	
	
	
 
		
			
	
	
		
		Well, the next day, I was able to log in again. However, I still am not able to run the wizard install. It still says no access privilege. 
I installed the plugin in the main admin of my multi-site. I will try and deactivate all other plugins. I have tried installing on the main site, as well as subsites.
I also installed buddypress on a standard WordPress install, and it works fine. I was able to run the install wizard, settings, and the whole nine yards. It’s wonderful by the way.
		
	 
	
	
	
 
		
			
	
	
		
		 @demetrius-pop ah the permissions problem. For the multisite installation, activating BuddyPress network-wide resolved that for me. 
Deactivate BP – from main site or subsite dashboard. Then go to Network Admin > Plugins and activate BuddyPress there. This will activate BP in main site by default. If you want BP in secondary site (subsite), add the following to your wp-config.php file before activating BuddyPress network-wide:
define ( ‘BP_ROOT_BLOG’, 3 );
change 3 to the blog ID where you want BP installed.
