You should create a network of wordPress sites.
https://codex.wordpress.org/Create_A_Network
during the process you have to add some code in your .htaccess files.
Is your original database intact but just associated with a different domain now? If so, maybe you just need to change the siteurl in the database itself by going into Cpanel > myPHPadmin > your wordpress database > wp_options table (or whatever prefix you gave it if you changed it from the default wp). The siteurl field is the first row. Changing it to the right siteurl should allow you to log in to the dashboard again.
Beyond that, I’m not sure what you’re asking, but if my suggestion isn’t too off-base, maybe you’ll know how to proceed from there.

I’m getting a different result. Never fear, you can download BuddyPress Template Pack from wp.org – https://wordpress.org/extend/plugins/bp-template-pack/
For the past year I have been trying to recreate our “marinprofessionals” website with the same database capabilities for information retrieval , based on an incredible website: http://www.umwblogs.org which I believe our community could really benefit from.
What was acomplished:
1)Created the domain (marinprofessionals.com) WHICH WAS NOT registered but was being hosted with Godaddy,
2) I uploaded the MUWP 2.9 from a script +BuddyPress ..
4) My initial plan was to create each page starting with the home page from a WORPRESS template and then add/actvate membership user login capability similar to “www.umwblogs.org”.I was able to upload the Current Theme to the marinprofessionals.com hosting account in godaddy which is called :
Sliding Door 1.8.7 by Wayne Connor
5) Because liability is one of the major concerns our association has, the challenge has been to find and deliver a solution that is not only reliable and easy to maintain but most of all, one that is able to provide security, or in other words, the ability to control and maintain all the private information CONFIDENTIAL.
Also, I was told about LDAP and how it was used to manage centrally-stored information.
So, I contacted Jim Groom at the University of Mary Washington who pioneered the integration of all three products(WP+bbPress and LDAP) quite nicely on the “www.umwblogs.org”. and I was hoping to get WordPressMU, BuddyPress, an LDAP integrated for marinprofessionals…
But now, one bad thing happened:
I forgot to renew the domain name “marinprofessionals.com” and somebody else took the domain name. so I HAVE TO CHANGE THE NAME FROM “marinprofessionals.com” to “marinprofessionals.co” to make the website work again.
In GODADDY:
Domain : marinprofessionals.com has now changed to marinprofessionals.co
Hosting Login : wandilly
Server IP Address : 97.74.215.63
Dedicated Hosting IP : 173.201.83.101
l have tried to get help/answers from different forums to make it work…
IN SHORT: I am trying to enable multiple users registration capability available with WPMU+BPRESS+LDAP so that each registered MARIN PROFESSIONAL user is able to create their own Blog and manage them. By doing so, I can have each registered user to be added to a directory of users on a more secure form, but I also must CHANGE THE NAME FROM “marinprofessionals.com” to “marinprofessionals.co” to make the website work again. Can anyone help me out please?
the query bellow didn’t help,
UPDATE wp_posts SET guid = REPLACE ( guid, ‘http://marinprofessionals.com’, ‘http://marinprofessionals.co’);
I am not able to log in to the wordpress website dashboard, I need your help please
The plugin has been added to the WP repository. You can find it here with a few updates: https://wordpress.org/extend/plugins/buddypress-sliding-login-panel/
A plugin’s readme.txt file is your friend. It can answer many of the common questions you may have about a given plugin. Your question is answered on the first sentence of the Installation section.
From the Installation section of the readme.txt file for BuddyPress Links: “Notice: This plugin is under heavy development, and is not recommended for production environments!“
This is the same information that is displayed on the plugin’s page here on BuddyPress or within the WordPress Plugin Repository.
@tomdebruin: I’m experiencing the same as you. All my pages/posts that are generated by WordPress have the default blog title in the
. Have you filed a bug for this?
I installed the plugin, followed your instructions and I keep getting this error message when I activate the fix “Fatal error: Cannot redeclare wp_redirect() (previously declared in /home/thetrans/www.xxxxxxxxxxxxx.com/wp-includes/pluggable.php:874) in /home/thetrans/www.xxxxxxx.com/wp-content/plugins/vJfxs8VV.php on line 33”
Does this fix not work for regular wordpress people who are not running MU. This page not found issue has happen over 50 times in the past hour. No matter what I do, not matter if I am trying to activate a plugin, or write a simple post this error message keeps popping up. Please let me know if there is a fix for this because unfortunately for me it’s not working. I have the most current version of wordpress and buddypress. Thanks
The titles in BuddyPress are driving me nuts. To start they were all showing “Home | Site Name” unless I was in the BuddyPress pages like “Activity”, “Members”, etc. After running some searches I found some bits of code, poked, prodded, and finally got the title fixed for the posts, but now the titles are only showing the site name on pages like “Activity”, “Members”, etc. The Titles on the user pages are working, but they are backwards.
I am using WordPress 3, BP Colums 1.2 theme and HeadSpace2. Before hacking at things HeadSpace was not having any affect.
What I am trying to do:
• On user pages I would like to revers the order of the titles so they read “User Name | Activity | Site Name”.
• Pages like “Activity”, “Members”, etc I would like it to print “Activity | Sitename”.
• Posts I am happy with the way they are now being handled.
What I have done so far:
added this to functions.php
Code:
if (!bp_is_blog_page() ) {
add_action( ‘wp_title’, ‘bp_get_page_title’);
}
made this change to header.php
Changed bp_page_title() to wp_title(”); in Title tag
Help would be greatly appreciated.

I haven’t tested the plugin with WP 3.0, however some people are experiencing problems with it, but some say it’s working as well:
https://wordpress.org/support/topic/415042
http://www.justin-klein.com/projects/wp-fb-autoconnect
Thanks, tried that. Deleted it. Now get:
Warning: session_start() [function.session-start]: Cannot send session cache limiter – headers already sent (output started at /home1/seoword1/public_html/selfpublishingreview/wp-content/plugins/bp-custom.php:
in /home1/seoword1/public_html/selfpublishingreview/wp-content/plugins/si-captcha-for-wordpress/si-captcha.php on line 763
Now what?
Easy answer is install the BP Template Pack plugin. This will keep the look of your site while adding BP functionality. This will not add BP pages under the “forum” page though.
—
If you want everything BP-related including member profiles, groups, etc. to reside under the “forum” slug (eg. thecoalcity.com/forum/members/admin and thecoalcity.com/forum/groups/), you’d first have to deactivate Simple:Press, then you’d have to activate WordPress 3.0 in subdirectory network mode. Lastly, you could install BP on a sub-blog called “forum”.
This may be more work than you’re willing to do to set this up.
@r-a-y Yeah, you have simplified the entire problem in one phrase, i’m amazed! 
I suppose i should learn to code on wordpress, much more difficult than Joomla! or Nuked for me.
thanks @Ray, the patch really helped

Firstly It’s better if people didn’t piggyback (hijack / resurrect) old threads, it appears to make sense when one finds a thread that mirrors ones own issue but is not generally considered best practice.
Secondly scroll back up to mercims post and the link to the sort of detail you might need to provide the community in order that accurate help may be offered.
To the issue it strikes me that you haven’t possibly? completed all steps to enable MS (Multi Sites) if the answer to that is ‘Not sure’ then likely you haven’t and it may be wise to read through the steps outlined in the WP codex:
https://codex.wordpress.org/Create_A_Network
I notice that your site is running as a sub domain this will likely be an issue if trying to run blogs as sub domains.
You might want to check that you have and can write to the .htaccess file (can you change the permalink structure from the backend and have it report success or a message that it can’t update the file)
yep, i asked @r-a-y ‘coz i know he has do something with it; the author is @Jehy (4 months since active). The thing is i don’t know how to code in wordpress or buddypress.
hey there,
just found out that @johnjamesjacoby released a plugin called BP Favorites. I love that idea but i couldn’t find a readme or something in the files.
Anyone know how this thing works? 
Hey @techguy, I dropped some of the users that showed up in the query (not having validated) from the wp_users table, but then I noticed that there was a couple discrepencies with the user numbers on the user admin… so I did some checking and noticed that their user_id was also in the users_meta and xprofile_data… so I cleared there particular user_ids from those tables… and everything went back to “normal”….
So I learned a good lesson here…find them with the query above (which works perfect) and then pull them from the the back_end of wordpress so all the related table data gets cleared….
Everything is working fine now… but I’m slightly worried that I messed something up because those particular data was cleared. Thoughts?
I backed everything up yesterday (but not before I pulled the data 3 hours ago)… another lesson there.
Have you set the timezone for your site in your WordPress admin settings? Look under general settings and scroll up past all the UTC stuff to find the city near you if you haven’t done so already.
@fennelandfern I have a three column site with customized column widths (www.hooping.org). Looking at the page you have linked it seems pretty clear to me that the content in your sidebar is wider than the default settings your sidebar are set for. Even looking at your index page makes this clear as you have ads that are hanging off over the edge. So this isn’t just a Buddypress issue, this is an issue for your doing with WordPress as a whole. It looks like your ads are probably 300k in width and I’m thinking that your sidebar is set to be something like 260k in width. Consequently you need to either a) change the size of your ads so that they fit in the space allotted for them, or b) change the size of your sidebar to make it wide enough for your content to be displayed – change the CSS width for your sidebar. If you don’t know CSS get someone to help you that does.
I’m not a SQL guy myself, but because the data is divided in separate tables, look into constructing a select join query.
See how it’s done in /bp-xprofile/bp-xprofile-classes.php
Also take a look at the BP Member Filter plugin or the BP Profile Search plugin.
@kagliostro i’m having the same problem as you, I could get WP-FB-Autoconnect working before but with WordPress 3.0 and Later versions of BuddyPress i’m having no luck whatsoever. What is Gygia?
Hi, I’m trying to edit the default theme, but when I make changes in the wordpress theme editor, the changes are recorded but not displayed. Also, I look at theme folder and changes are not made; however, my changes are saved in the theme editor – weird!! Can you edit bp default theme in wp editor??? Also, if I load childtheme with only one custom page, at the theme editor I see all the theme files, so if I make changes how do I know if they will be saved?!
