You might just need to “jog” system up a bit. Go back to the Group > Admin where you enabled forums, and disable forums, and Save. Go to another page then go back to Group > Admin and enable forums and Save.

		Check two areas:
– server: see if there’s a bb-config.php file at root of your WP install, same level where you find the wp-config.php
– database: check if 7 tables were generated in your database or not. See examples of bbPress tables in either single WP and WP multisite at https://codex.buddypress.org/getting-started/installing-group-and-sitewide-forums/3/#bp-forums-db
		
	 
	
	
	
 
		
			
	
	
		
		I do have bb-config.php at my root directory.
But do i need to install the site wide bbPress forum in order to make the group forum works? I just want the forum in the group only.

No. I never said that. I just linked to area where there’s a screenshot of the database with 7 forums tables so you could compare yours. Were the 7 bbPress tables for the forums generated in your database?
Also, double-check if the database information in your bb-config.php is correct.
		
	 
	
	
	
 
		
			
	
	
		
		Yeah, I found the problem, turn out is the bb-config.php misconfig…..
Anyway, thanks  @mercime for your help.
