OvenCMS problems

I have installed OvenCMS according to the instructions. The index page displays just fine, but all other pages (such as http://localhost/ovencms/containers/display/2) raise a 404 error. Anyone know how I resolve this?

many thanks!

After install I have the same problems, is something about urlmanager, try to add index.php in the url and change in config.php : ‘showScriptName’ => true,
