Hi,
Thank you for the question.
yes, both of these are doable.

here is some sample code for that.

// disable testimonials component for some users.
add_filter( 'bp_testimonial_enabled_for_user', function( $is_enabled, $user_id ) {

	// process
	return $is_enabled;
}, 10, 2 );
/// limit show can write
add_filter( 'bp_testimonial_user_can_write', function($can) {

	if( ! is_user_logged_in() ) {
		return $can;
	}
	// in case you want to find the user for whom testimonial is being written
	// it is displayed user.
	// $displayed_user_id = bp_displayed_user_id();
	// check for current user
	if( current_user_can('read') ) {
	// update $can to true/false/
	}

	return $can;
});

Hope you can adapt it for your purpose. Please let me know if you want me to put an example with roles?

Hi Herimanana,
Welcome to the BuddyDev support forums.

I don’t see any proper way to do it.

You may randomize but then you will need to track that the same activities should not be shown repeatedly on load more. Also, if the randomness is enabled, you may want to maintain the freshness of the stream somehow. This is doable but we don’t have enough resource or interest in it in currently.

Hi,
Welcome to BuddyDev support forums.

Is it about MediaPress or Activity Plus reloaded?

Our plugins are currently tested with the default post form. You have a customized form that uses visual text editor and that might be the reason.

Please let me know which plugin you are using and our team will try to test it within a week a get back to you(sorry, we are short on support for this week).

Hi Giuseppe,
Thank you for the question.

Probably the extra data that you are adding using custom code is pushing the buttons leading to this. Since you are using a custom theme, I will suggest contacting theme authors for help. They can supply you custom css(and may be advise to wrap the code block in additional section) to fix it.
