You can change bbpress theme at admin area
		
	 
	
	
	
 
		
			
	
	
		
		Themes have to be put in /forum/my-templates/theme-name/, not in bb-templates. So you would put the Crystal files in /forum/my-templates/crystal/ (make the my-templates folder if you don’t have one).  Then go to the “admin” area, click on “Presentation” then click on the theme you want.

		You are no keymaster, login as keymaster and it will appear
		
	 
	
	
	
 
		
			
	
	
		
		I think you have a problem!
You’re logged in as “admin”? “admin” is the only user?
Did you change the account? Your account needs to have the “Keymaster” role! Keymaster > Administrator. Only the Keymaster can change the theme I think.
If you have changed the role of the “admin” account to Administrator, you may have to reinstall.

		AstRonot: The keymaster is the user that was registered when you installed bbPress, unless you changed it afterwards.
