I ran the White Space checker in IPB and got an error in this file:

sources/loginauth/convert/auth_sha256.php has whitespace at the beginning or end of the file

It looks like you forgot to add the "?>" at the end of the code

OK, sorry didn't see it was already reported. So is it normal for the white Space Checker in IPB to detect it as a file that has a White Space?

Yes, it's normal for this file and does not indicate a problem.
