Replying well after the fact to help any other Google searchers who come across this page:

Add something like the following code to your theme’s functions.php file:

add_action( 'bp_members_directory_order_options', 'bp27845_add_random_order_option' );
function bp27845_add_random_order_option() {
	echo '<option value="random">' . __( 'Surprise me!', 'buddypress' ) . '</option>';
} // end bp27845_add_random_order_option

This code takes advantage of the bp_members_directory_order_options action hook to insert a new option, which then sets bp_has_members()‘s type to random (the value we’re sending).

It is possible.
I’m not aware of a plugin for that.
So it will require custom code.
You can hire somebody here:

You can’t override core files.

Undo the changes you made to /bp-messages-classes.php

Copy
bp-templates\bp-legacy\buddypress\members\single\messages\single.php
to your child theme so that the dir structure looks like this:
your-theme\buddypress\members\single\messages\single.php

Then in single.php, change
if ( bp_thread_has_messages() ) :
to

<?php  
	$args = array(
	   'order'     => 'DESC'
	);
if ( bp_thread_has_messages( $args ) ) : ?>

WPTouch doesn’t load anything less. It is essentially just another theme with a mobile UI. Also, the template files of BuddyPress are not 100% responsive and do not fit perfectly inside WPTouch. You would have to make them look proper.

If load times are slow then it could be that you are just loading too many files. This is an issue on even desktop browsers because more people visit websites from mobile browsers than from a pc now. I suggest you deal with making your regular site more data efficient in addition to serving up a better visual for small screens.

This snipped section from the link mercime provided, as can be seen it states existing instals using the bp-default theme will still use it it’s not going to suddenly stop working but changing to the theme compatibility process is in best interests.

If you are already using bp-default, either directly or as a parent theme, don’t worry. BuddyPress 1.9 will detect that you need bp-default, and will continue to register it with WordPress. Note that if you switch away from a bp-default theme (say, for testing), the theme will disappear from Dashboard > Appearance. If you need it back, add the following line to your bp-custom.php file:

add_filter( 'bp_do_register_theme_directory', '__return_true' );

EEK!

There have been many changes between these versions. Did you by chance backup your database before upgrade? You need to do an incremental upgrade. Also, current BP doesn’t use it’s own forum anymore and you have to install bbPress separately.

There is also a plugin that does this. It’s old, but it still works:

Thank you @mercime for your warning, I am not very happy with the fact that bp-default is going to be a past, I like that theme, I thought that I will avoid a lot of problems staying with default theme, but for sure developers knows what they do, so I will start to think about the different theme, and will do everything to be a responsive from the start, instead to continue to maintain and edit this one. I would welcome some expert’s recommendation which one should for buddypress fit best now.

@hajhaj there are different ways to implement a new layout for all BuddyPress pages. Check out how it was done for the WP default themes at https://codex.buddypress.org/themes/bp-theme-compatibility-and-the-wordpress-default-themes/

@craigola Do you mean you want to set up different account types and that one kind is that for children? If so, have you checked out https://wordpress.org/plugins/buddypress-user-account-type-lite/

Unfortunately, there don’t seem to be hooks to avoid recording such activity.

And unfortunately you can’t suppress the display of only some group activity stream items – it’s groups or no groups.

So you have to filter all activity stream items – they all use the same code.

Take a look at the filter hook at the bottom of
function bp_has_activities
in
buddypress\bp-activity\bp-activity-template.php

This thread should give you some code to start with:
https://buddypress.org/support/topic/is-it-possible-to-hide-or-remove-activity-in-the-main-activity-stream-from-certain-groups-while-keep/

In case anyone is having the same problem, the solution i came up with was to make a plugin using the buddypress members widget core code, as @danbpfr suggested. That widget was not breaking things, so once i had a plugin version i was able to add some of the extra things that were in my original loop.

I posted a note
– In the front end Activity feed at 3:40 pm (correct time)
– Dashboard > Activity shows 10:40 am (5 hours backwards)

Someone posted a note
– In the BBpress forum at 10:59 am (correct time)
– Front end Activity feed shows 3:59 pm (5 hours forward)
– Dashboard > Activity shows 10:59 am. (correct time)

@4ella since you’re using the BP Default theme, please be aware of http://bpdevel.wordpress.com/2013/11/13/the-future-of-the-bp-default-theme/

Going back to the issue at hand, your main navigation links are showing up that way because of the responsive style included in the BP Default theme:
lines 43-50 https://buddypress.trac.wordpress.org/browser/tags/1.8.1/bp-themes/bp-default/_inc/css/responsive.css#L43
lines 211-221 https://buddypress.trac.wordpress.org/browser/tags/1.8.1/bp-themes/bp-default/_inc/css/responsive.css#L211
