Site blank: stderr: PHP Fatal error: Class 'Country' not found in /domains/mydomain.nl/pu

This morning my shop showed a blank page, frond- and backend.

 

In the error.log of my server i see this:

 

 

 

client denied by server configuration: /domains/mydomain.nl/public_html/classes/Country.php, referer: http://kofferbakmatopmaat.nl/classes/Country.php

 

client denied by server configuration: /domains/mydomain.nl/public_html/tools/swift/Swift/Connection/Rotator.php, referer: http://kofferbakmatopmaat.nl/tools/swift/Swift/Connection/Rotator.php

 

 

PHP Fatal error: Class 'Country' not found in /domains/mydomain.nl/public_html/config/config.inc.php on line 142

 

 

I fixed it by restoring a backup but i would like to learn how this could happen.
