First of all: https://buddypress.org/forums/topic/when-asking-for-support
Secondly: I am assuming you are using the default BP 1.1 theme for the moment – are you? If not, use the default theme until you have it all working. Make sure it is in /wp-content/themes/. Activate the theme in the normal way and select it; this warning message should go away.
Sorry, but can you please explain it more easy? Please excuse me as I’m new to BuddyPress. What do you mean by ‘using the BP1.1 theme’? Do I have to activate the BuddyPress Parent theme for my site?
Hi abcaa6!
There are just a few themes right now that are meant to work with 1.1 unless you make som modifications. So (I assume) DjPaul is advising you to use the default theme template and not others (or the only other one found at buddypress.org/extent/themes/).
The parent theme + its child is one of the few that works right now. Unless you rebuild it yourself:

I’m off trying that myself right now. Cya folks!
Then what do I do if I want to use other theme? I don’t want people to see some chunks of boxes when they come to my site!
Hi again!
Read this:
“I’ve used a WordPress theme for my blog with the default BuddyPress member themeâ€

You’ll have to edit things and if you’re not comfortable with that you’ll probably need more help than you can get here. 
I don’t know your level of knowledge. Search around the forums and read up on the topics you need. I haven’t had answers to all my questions here in the BP-forums. You’ll have to search for some of them on your own.
Thanks Tore. You really helped.
Just like you, I searched all over the BP Forum for my questions but found no answer for all of them.
Thanks for your advice though.. 
BTW, Do you run a WPMU+BP site? If yes, can you provide the link to your site so that I can check it out as an example?
Great!
I’ve got a closed website so there’s nothing to show.
Same thing here. Downloaded latest WPM (version 2.8.4a) and installed. Next up I installed BP. Followed the instructions here: https://codex.buddypress.org/getting-started/setting-up-a-new-installation/ to the letter, but now have the following showing under Buddy Press->General Settings:
Your currently active theme is not BuddyPress enabled.
Visit https://buddypress.org/extend/themes/ to browse themes that include support for BuddyPress features.
Regs.
Make sure that you have moved the default BP parent-child theme files into /wp-content/themes/. That means that the “bp-default†and “bp-sn-parent†folders should reside right under the /themes/ directory.
Then make sure that you have activated them as described in point 5 of the section entitled “Installing BuddyPress” in the link you provided above.
