I knew that was the plugin of buddypress. However, once I delete this pludgin, and I access to my wordpress, it will display something like: files of buddypress are missing….. I don’y know how to disable the plugin of buddypress><!
Just added this at the bottom of Codex FAQ page https://codex.buddypress.org/getting-started/faqs/
Feel free to improve wording 
Can I run multiple instances of BuddyPress in a WP Multisite installation?
No. BuddyPress can only be activated once in either the main site or a secondary blog of a WP Multisite installation .
I tried to install buddypress, followed all the instructions but it says…
Plugin could not be activated because it triggered a fatal error.
Warning: require_once(/data/24/2/13/97/2339749/user/2568937/htdocs/wp-content/plugins/buddypress/bp-core.php) [function.require-once]: failed to open stream: No such file or directory in /data/24/2/13/97/2339749/user/2568937/htdocs/wp-content/plugins/bp-loader.php on line 20

How can I fix this? Can someone please help?
Dive in! You really do need to have a basic grasp of HTML/CSS if you’re going to get anywhere with WP/BP.
…and don’t forget to allow yourself to have fun while you’re pulling out your hair! 
Im really sorry im trying to help these kids and don’t really know anything ab0ut this website creating stuff i study, honestly, atleast 10 hours everyday. since sept 22 2010. I really want to make this site cool and haven’t got anywhere except downloading themes and plugins. plus im doing it all alone with out a clue. i more than appreciate all your advice and prompt responses. im sure you have more important things to do. im gonna stic my head back in these HTML & CSS teach your self books. Thanks again for everything really
In “Community”, I only see Activity, Members and Groups. In “My Account”, I see Activity, Profile, Messages, Friends, Groups, Albums, Settings, Logout (with appropriate subnavs). The Create a Group button is only seen in the Group directory (where it should be), but you can grab the code from groups/index.php and add it to other templates too if you prefer.
yeah i tried to fix the forum thing then it gave me issues which i posted in another support topic.
it tells me files not found
then i tried to go with the other option and followed the instructions (save files to bb-config.php) still nothing
you used the “community” section right….i see the “community” and the “my account”. both listing the same things only the new “community” bulilt is the only 1 i can create a group in. but i guess that wint matter after i fix all this up
I just created an account on your site and was able to create a group just the way it’s supposed to be done (the “Create a group” button is in the Groups directory).
Forums aren’t enabled yet on your site, are they? You can do that in your WP backend under “Buddypress” > “Forums Setup”.
i see a “buddymatic” theme says it comes with 2 ready child themes……..or should i stick to suffusion?
Saving Our Boys Society
WARNING!!! lol, i have put everything back to default and it looks a little crazy so this is why im trying to hurry and fix it all
Ah yes, child themes are one of the MOST important things to learn when it comes to BP.
Here’s a link to the codex tutorial:
https://codex.buddypress.org/theme-development/building-a-buddypress-child-theme/
Could you post a link to your site? I could register there and see if I can help out.
If i had any hair right now i swear id pull it all out…..can just delete everything and start from scratch? well everything but wordpress. my theme (suffusion) and all plugins? it says i need to create a child theme 1st….gotta figure out that 1 as well….im really sorry man. and you have been more then helpful. im just really new and just when i thought i knew something BANG!!! im smacked with the idiot feeling
ok, with the new installation i have a new community menu in the admin bar. in this menu there is only three subs activity, members and groups. now in the new “community” menu i see the “create” a group option in groups in my original “my account” i dont have the option to create a group but more subs (profile, settings, logout, albums and all there child pages. i hope you understand all that….

Gotcha! Here’s how…
1- Enable “Hide Main Theme Nav”, “Add WordPress pages/menus”, “Add Buddypress components” and “Scroll with pages”.
2 – Go to “Sizes & Position” and adjust the “Overall navbar width” to the width of your template.
3 – Play around with “Vertical offset” and “Horizontal offset” until you get it positioned about where you want it.
4 – Save settings.
5 – Now go to “Appearance” > “Menus” and select the WP3 custom menu you want at “BP-WP-Navbar Menu 1”
6 – Click “Save” at “Theme locations” and “Save menu”
7 – Check your site and refresh a page.
8 – Repeat, lather & rinse until you get it “just right”.
9 – Have fun! 
ok now im lost this is completely the opposite of what i asked for….lol
i wanted to move the bp admin bar to my sites nav bar. i just have an extra menu with community on the BP admin bar
