BuddyPress.org

Figure out the basics of plugins first, https://codex.wordpress.org/Writing_a_Plugin, and then try AJAX https://codex.wordpress.org/AJAX_in_Plugins

Typically, you start by creating a plugin and go from there. Have you written plugins for WordPress before? Also, what are you trying to do?

You’d have to adapt group codes to do that, much like this plugin did https://wordpress.org/extend/plugins/bp-group-reviews/

I don’t think so, because BuddyPress doesn’t make use of WordPress roles or capabilities yet

Now that BuddyPress runs on WordPress in single blog mode… what do people think about running BuddyPress on a shared host in single blog mode with a community of maybe 175 members. Again… there would just be the ONE parent blog. No sub-blogs.

There’s something like that already. Just needs to be updated https://wordpress.org/extend/plugins/buddypress-badge/

@alexbdd Following the instruction in this BP codex article https://codex.buddypress.org/theme-development/wordpress-to-buddypress-theme/

Go to server and download the template folders/files transferred by BP Template Pack plugin process to your active WP theme folder down to your computer.

Open up activity/index.php

change this at the top, replace:
`

`
with
`
<?php
get_sidebar();
get_footer();
?>`

Save file and upload to server following the directory structure. You need to do the same thing in the next 12 files.

There’s no cache (only WordPress’) but the activity stream content is written once into the database. You’ll have to go into the database, bp_activities table, and make changes manually.

If you want to completely disable public registrations, and only want to set up a invite only BuddyPress community, check out this plugin as well: https://wordpress.org/extend/plugins/wordpress-mu-secure-invites/

Should work in combination with the plugin Mercime mentioned

https://wordpress.org/extend/plugins/invite-anyone/ works in current BP/WP versions.
and/or http://buddydev.com/buddypress/buddypress-friends-suggestions-widget-help-your-users-to-build-their-network-faster/

1) You could import/export all posts and comments from LJ to WordPress site. https://codex.wordpress.org/Importing_Content#LiveJournal. Didn’t check what WP version the script was compatible with, but you can download WP versions from this page
and upgrade to later version later.
https://wordpress.org/download/release-archive/

Currently, there are no scripts to convert these into a BuddyPress group setting. You might have to hire someone to consult with or to implement that as well as import users automagically as BP/WP users along the way.

#2 and #3. Haven’t seen any indication that this can be done except probably with RSS imports/exports. I suggest you clear up #1 first before moving along these questions.

= I found some article and plugin for custimizing WP theme for BP ==

That’s one way, using your WordPress theme and installing the BP Template Pack plugin to transfer BP template files (for BP component pages) plus ajax and js goodness to make your WP theme BP-compatible.

Another way is to create a child theme of the bp-default theme
https://codex.buddypress.org/theme-development/building-a-buddypress-child-theme/
then adjust via CSS only to change layout and colors or do more than that.

== I can no longer reach the main index template from the editor as a Network Admin ==

If you mean files in child theme of bp-default theme, that has been reported
https://trac.buddypress.org/ticket/3096
https://core.trac.wordpress.org/ticket/16744

If on other themes, please provide more information or steps to replicate problem.

What is LJ? If it’s another group or forum software, you will need to search for a LJ to wordpress bridge. Otherwise, there is no other way to import, unless there is a feature with the LJ software.

or https://buddypress.org/community/groups/buddypress-announce-group/
but needs updating

You might want how to look at how it’s done in this plugin – not updated for a while

=== two themes on the same wordpress install ===

If you mean use two themes for a single WP install or a single site of a WP multisite install. No. I seem to recall a plugin that was supposed to do that a long time ago, but I doubt if it had even been upgraded nor if it will work with BuddyPress.

What can be done right now is to create a child theme of bp-default then copy over the “regular” WP pages from bp-default theme into your child theme like index.php, page.php, single.php etc. and call a different header, footer, sidebar and even styling for those specific pages.

I have this issue as well. Just migrated from a shared hosting environment to a VPS. This is the only change I’ve made. My stats:
Wordpress 3.1
Buddypress 1.2.8
Default Favicons
Root Directory
Core files untouched

Plugins:
BuddyPress Template Pack
W3 Total Cache with Object Cache & Minify active
BP-Album+
MarkItUp RTE (manual JS plugin install)

So the issue is only on some groups. On both groups that work properly and don’t, there are no obviously problematic HTML validation errors. On the groups that are problematic, MarkItUp doesn’t appear on the textarea, and when “reply” is clicked, the page reloads (hashtag visible), and no comment box appears. Oddness. Thoughts?

Use a WordPress theme and install the BP Template Pack plugin where you have to change HTML structure to use your WordPress theme’s HTML structure.
