@Camden, elgg api for getting avatars has changed, so you need to create a new ticket on comet chat to fix this error, 

This is not elgg error!

Thanks

We usually alter our integration making the DB_AVATARFIELD constant reference the username. Looks something like this:

define('DB_AVATARFIELD', " ".TABLE_PREFIX.DB_USERTABLE.".".DB_USERTABLE_NAME." ");
...

/**
 * Get user avatar URL
 *
 * @param string $userId Elgg username
 * @return string
 */
function getAvatar($userId) {
    $elggUsername = urlencode($userId);
    return BASE_URL . "../avatar/view/$elggUsername/tiny";
}

@Steve Clay, hey when you have added page handler to get avater? ops i didn't even realize it!
