When I try to install SilverStripe 3 on my hosting I get this warning:
fileinfo should be enabled in PHP. SilverStripe uses it for MIME type detection of files. SilverStripe will still operate, but email attachments and sending files to browser (e.g. export data to CSV) may not work correctly without finfo.
Support has told me that fileinfo is no longer a module and is built into PHP? I can't see it in the list of modules in phpinfo().
Is this a bug with SS (i.e. is it wrongly reporting an error) or is it a configuration issue?
