Is it live?
Do you have .htaccess file in the root of your site? The same place, where you have wp-config.php file. If you have .htaccess – please post here its content (you can use pastebin.com to enter code details therу and post here just a link).

@lorddunvegan
Change permalinks to just /%postname%. Make sure you have a published Groups page in admin area and /groups/ link on front-end is accessible and display list of groups (or no groups message).

There is such setting: http://take.ms/iD38m
It should be checked.

And there is also such ticket in trac: https://buddypress.trac.wordpress.org/ticket/6482
It will allow comments syncing between activity stream item and posts (so they will appear in both places – very handy). This feature will be included into upcoming (in March) BuddyPress 2.5.

Place this code in bp-custom.php or functions.php of your theme.

if ( ! is_super_admin() ) {
add_filter( 'show_admin_bar', '__return_false' );
}

This is a bug in BuddyPress.
Here is a new ticket: https://buddypress.trac.wordpress.org/ticket/6846

bp_get_activity_content_body – that’s the filter you might need.
See function bp_get_activity_content_body() for details.
General idea (you will need a bit of regexp knowledge):
1) search in activity content for <iframe keyword.
2) if it exists – wrap it with the div you need
3) That’s it. This will be done on a fly for each item in activity…[Read more]

Try visiting this link inside your site /wp-admin/tools.php?page=bp-tools and recalculate members number.
Also the difference might be in the way plugins are counting – with or without activated users, with or without spam users etc.

Oh, and it seems there is a plugin-based solution for that: http://wptavern.com/conditionally-hide-buddypress-profile-field-groups-based-on-user-role

Out of the box there is no such setting.

You can take a look at this solution: Hide Profile Field Group from Specific Member Type

I didn’t find any info about this. So the only option – hire somebody to do it for you.

If you are talking about site-wide notices – there is a default widget called “(BuddyPress) Sidewide Notices” that just displays notices. You should create them on “Profile -> Messages -> Compose” page, with “This is a notice to all users.” checkbox checked. Make sure you have BuddyPress Message component activated.

http://upwork.com/ is the largest. Lots of great developers there.

I don’t see my fix in the source code of the /register page.
Does your theme have /members/ or /buddypress/ directory? If yes, please give me content of the file /members/register.php or /buddypress/members/register.php.
If there is no such file, – give me the content of a file (and its name) where you put the code I gave you. You can use…[Read more]

No, it should not matter. General rule – in the and of the file 🙂

After rereading I see that you have a different request. But check that ticket anyway 🙂

You should definitely take a look at this ticket in BP trac – #6592.
It’s all about the future of emails in BuddyPress. Please test and provide your feedback there in a ticket. Thanks a lot!

Are you talking about CDN?
It’s not an option for BP plugin. Some sites are developed in Intranet – they don’t have access to Internet at all. So CDN won’t be available for them. You can easily use cloudlflare or any other CDN provider to save there your assets.
