This is caused by an PHP extension not loading properly. Hype doesn't export PHP, so this isn't strictly caused by Hype (though I could imagine situations where a server config might be invoking PHP at some point).
It is having problem loading the fileinfo.so extension. From what I can tell this is a standard PHP extension, so it is probably the case that your install is somehow corrupt. If you can, I would simply recommend reinstalling PHP or that extension if possible.
