I have just downloaded SilverStripe. I have installed with the web wizard, and everything went ok. Now when I log in, and access to the admin, section "Files & Images" and "Security" I get this error:
FATAL ERROR: DataObject::get_by_id passed a non-numeric ID #r0wJg6KZt3A=
At line 1596 in /var/www/silverstripe/sapphire/core/model/DataObject.php
Also, when i access any page on the "Site content" tab, the editor says "This page doesn't exist". I used BlackCandy template to install.
How can i solve this error?
Ubuntu Gutsy 7.10
