Total destruction after upgrading to 1.10

Piwik no longer loads and I get this message, with slight variations repeated over and over.

There is an error. Please report the message (Piwik 1.9.2) and full backtrace in the Piwik forums (please do a Search first as it might have been reported already!).

Warning: fread() expects parameter 1 to be resource, boolean given in /srv/www/stats.dailyanarchist.com/public_html/core/Http.php on line 340
