language/en/memberlist.php is have "Last visited" is mean error.

'VISITED' => 'Last visited',

This is not last visit, this is last activity.

This is my easy referance:

$last_visit = (!empty($data['session_time'])) ? $data['session_time'] : $data['user_lastvisit'];  

If user is online; "last activity" = "session time", session time is change on every page change. If user is offline "last activity" = "last visit", because if session is finish, session time fill on last visit time.

session.php

// Update the last visit time$sql = 'UPDATE ' . USERS_TABLE . '    SET user_lastvisit = ' . (int) $this->data['session_time'] . '    WHERE user_id = ' . (int) $this->data['user_id'];$db->sql_query($sql);  

Then;

language/en/memberlist.php is :

'LAST_ACTIVITY' => 'Last activity,
