Hi Dandy,

Please replace the old code with the following code and let me know if it works or not.

add_action( 'bp_setup_nav', 'buddydev_setup_modified_nav', 20 );
function buddydev_setup_modified_nav() {

	$bp = buddypress();

	bp_core_remove_subnav_item( buddypress()->activity->id, 'just-me' );

	$bp->members->nav->{'activity/mentions'}->position = 40;
	$bp->members->nav->{'activity/favorites'}->position = 30;

	if ( bp_is_active('groups') ) {
		$bp->members->nav->{'activity/groups'}->position = 20;
	}

	if ( bp_is_active('friends') ) {
		$bp->members->nav->{'activity/friends'}->position = 10;
	}

	bp_core_new_nav_item( array(
			'name'		                => __('Home','buddypress'), //replace with your name
			'slug'		                => 'home', // slug must be unique
			'screen_function'	        => 'buddydev_show_activity',
			'position'                  => 1, // unique
			'default_subnav_slug'       => false,
			'show_for_displayed_user'   => true, //Whether the nav item should be visible when viewing a member profile other than your own
		)
	);

	bp_core_new_nav_default (
		array(
			'parent_slug'       => buddypress()->activity->id,
			'subnav_slug'       => 'friends',
			'screen_function'   => 'bp_activity_screen_friends'
		)
	);

	if ( bp_displayed_user_domain() ) {
		$user_domain = bp_displayed_user_domain();
	} elseif ( bp_loggedin_user_domain() ) {
		$user_domain = bp_loggedin_user_domain();
	} else {
		return;
	}

	$parent_slug          = bp_get_profile_slug();
	$slug = trailingslashit( $user_domain . $parent_slug );

	bp_core_new_subnav_item( array(
		'name'          => __( 'Personal' ),
		'slug'          => 'just-me',
		'parent_slug'   => $parent_slug,
		'parent_url'    => $slug,
		'position'      => 0,
		'screen_function' => 'buddydev_show_activity'
	));

}

function buddydev_show_activity() {

	add_action( 'bp_template_content', 'buddydev_render_screen_my_activity' );
	bp_core_load_template( 'members/single/plugins' );

}

function buddydev_render_screen_my_activity() {

	?>

	<div class="item-list-tabs no-ajax" id="subnav" role="navigation">
		<ul>

			<li id="activity-filter-select" class="last">
				<label for="activity-filter-by"><?php _e( 'Show:', 'buddypress' ); ?></label>
				<select id="activity-filter-by">
					<option value="-1"><?php _e( '&mdash; Everything &mdash;', 'buddypress' ); ?></option>

					<?php bp_activity_show_filters(); ?>

					<?php

					/**
					 * Fires inside the select input for member activity filter options.

					 * @since 1.2.0
					 */
					do_action( 'bp_member_activity_filter_options' ); ?>

				</select>
			</li>
		</ul>
	</div><!-- .item-list-tabs -->

	<?php
	if( is_user_logged_in() && bp_is_my_profile() ) {
		bp_get_template_part( 'activity/post-form' );
	}
	echo "<div class='activity'>";
	bp_get_template_part( 'activity/activity-loop' );
	echo "</div>";
}
