I have a fresh new installed Pimcore 1.4.2 (Build 1500). The very first thing I do is to create a new folder in the asset menu. I fill in the name and then I get an error "Server threw exception - could not perform action". In Firebug I get
.<b>Fatal error</b>: Uncaught exception 'PDOException' with message 'SQLSTATE: Integrity constraint violation: 1062 Duplicate entry '2-asset' for key 'PRIMARY'' in C:\...\pimcore\lib\Zend\Db\Statement\Pdo.php:228
I tried it with PDO and with mysqli (which I can decide at the beginning of the installation) and serveral new instances. Even when I make an update to Build 1593.
I am on a windows system with Zend Server CE. I tried both MySQL 5.1 and MySQL 5.5, no difference.
I read about optimizing and analysing the database in MySQL, but that didn't solve this.
I really want to use pimcore, but I can't do anything without creating new sites or asset folders.
Hope somebody can help me.
