Constructor cannot be static after Update (5 replies)

After the update to Version 2.6.0 I get get a white page when I try to access Piwik.

The server error log says:

[Fri Sep 05 13:43:31 2014] [warn] [client 2.206.**] mod_fcgid: stderr: PHP Fatal error: Constructor Piwik\\Factory::factory() cannot be static in */piwik/core/Factory.php on line 60, referer: *

I use PHP 5.3 on an apache server.

Any ideas what causes this problem?
