[Forum] Suspect File Versions not recognizing index.php and forum.php

[Gabrielt]

ACP, Maintenance, Diagnostics, Suspect File Versions. I run this option after upgrading to 4.0.1 from 3.8.4 PL1 to make sure I don't have obsolte files hanging around our HDD and to my surprise I found this:

forum.phpFile not recognized as part of vBulletinindex.phpFile does not contain expected contents

Opening these two files I can clearly see the vBulletin 4.0.1 header on them. Is this a bug? Please advice.

Thanks,
Gabriel.
