So the warning raised was:

> Undefined index: latest-user

The code flagged was:

"%LATEST_USER%" => $this->stats["latest-user"]

I did a bit more research and stumbled upon:

`
if( $this->parent->option[‘last_user’] === “on” ) {
$HTMLOutput[“last_user”] = $this->section_latestuser();
}
`

At first I thought that latest-user needed to be changed to last_user, or vice-versa. But I continued the research of the code and arrived here:

`
array(
‘id’ => ‘last_user’,
‘label’ => __( ‘Latest Registered user’, ‘bbpress-improved-statistics-users-online’ ),
‘description’ => __( ‘Display the latest user to register to the site?’, ‘bbpress-improved-statistics-users-online’ ),
‘type’ => ‘checkbox’,
‘default’ => $this->defaults[‘last_user’],
‘class’ => ”
),
`

I decided to have a look at my bbPress Advanced Statistics settings and this was actually unset. I have now switched it on:

Now the warning does not display. Also, it then occured to me that the code has this line:

$this->stats = $this->stats_extra( $activity );

That function does this:

`
private function stats_extra( $activity ) {

if( $this->parent->option[“bbpress_statistics”] == “on” ) {
// Add the bbPress Statistics
$activity[“bbpress”] = $this->get_formatted_statistics();
}

if( $this->parent->option[“last_user”] == “on” ) {
// Get the HTML latest usser
$activity[“latest-user”] = $this->get_latestuser( true );
}

if( $this->parent->option[“most_users_online”] == “on” ) {
// Get/set the most users ever online, users the active online users
$activity[“most-users”] = $this->get_mostusers( $activity[“count”][“active”] );
}

return $activity;
}
`

Therein is the problem. This function is conditionally populating the stats array based on user options. Makes sense, but, this function, makes assumptions:

`
private function allowed_tags() {
// Store all of the strings currently replace
$this->_tags = array(
“%MINS%” => $this->parent->option[‘user_inactivity_time’],
“%COUNT_ACTIVE_USERS%” => $this->stats[“count”][“active”],
“%HOURS%” => $this->parent->option[‘user_activity_time’],
“%COUNT_ALL_USERS%” => $this->stats[“count”][“inactive”] – $this->stats[“count”][“guests”],
“%COUNT_ALL_GUSERS%” => $this->stats[“count”][“guests”],
“%COUNT_ACTIVE_GUSERS%” => $this->stats[“count”][“guestsa”],
“%USER_USERS%” => _n(“user”, “users”, $this->stats[“count”][“active”], ‘bbpress-improved-statistics-users-online’),
“%GUEST_GUESTS%” => _n(“guest”, “guests”, $this->stats[“count”][“guestsa”], ‘bbpress-improved-statistics-users-online’),
“%ALL_USER_USERS%” => _n(“user”, “users”, $this->stats[“count”][“inactive”] – $this->stats[“count”][“guests”], ‘bbpress-improved-statistics-users-online’),
“%ALL_GUEST_GUESTS%” => _n(“guest”, “guests”, $this->stats[“count”][“guests”], ‘bbpress-improved-statistics-users-online’),
“%USER_RECORD%” => $this->most_users( “record” ),
“%USER_RECORD_DATE%” => $this->most_users( “date” ),
“%USER_RECORD_TIME%” => $this->most_users( “time” ),
“%LATEST_USER%” => $this->stats[“latest-user”]
);

// Apply any filters that may have been applied to the list of existing tags
if( has_filter(‘bbpas_replacement_tags’) ) {
$this->_tags = apply_filters( ‘bbpas_replacement_tags’, $this->_tags );
}
}
`

I will be upfront here – I don’t know how to adjust the code so that it will not raise a warning when the Last Registered User setting it not checked. As a result I switched it on.

I just thought i would throw my findings out here as someone might be able to provide the tweak to make it correct.

have a good day!
