attributes_controller.php - 500 (Internal Server Error)

Hi guys

i´m pretty new to ZEN, but i have installed the latest version av zen and when i´m trying to access the 500 attributes_controller.php throu the admin control panel it just gives me a internal 500 error. It has been så since the installation.

I havent installed any mods or anything else.

the file has 755 CHMOD

any idea what that could be?

thanks in advance!
