Not Compatible with PHP 5.4 and above

Hi! For everyone who experienced the same issue, it might help if I paste my problem and solution here:

Errors with PHP > 5.4

1. Fatal error: Call-time pass-by-reference has been removed; If you would like to pass argument by reference, modify the declaration of apply_filters(). in C:\xampp\htdocs\buddy\wp-content\plugins\buddypress-followers\bp-follow.php on line 720

// solution
// in line 720
  return apply_filters( 'bp_follow_is_following', (int)$follow->id,    &$follow );
// change it to:
 return apply_filters( 'bp_follow_is_following', (int)$follow->id, $follow );

2.Warning: Creating default object from empty value in C:\xampp\htdocs\buddy\wp-content\plugins\buddypress-followers\bp-follow.php on line 38

Warning: Creating default object from empty value in C:\xampp\htdocs\buddy\wp-content\plugins\buddypress-followers\bp-follow.php on line 42

// solution

    $bp->follow = new stdclass();
    $bp->follow->followers = new stdclass();
    $bp->follow->following = new stdclass();

Thanks
