Blank Screen After "save" In Bo .. Need Help

[Deluxdeal.dk]

Hello Community.

 

I just installed prestashop on my domain.

Everytime i press save on anything in backoffice, cant even press "use theme". I get blank white screen with following error code:

 

Fatal error: Uncaught Error: Access to undeclared static property: Validate::$values in /var/www/deluxdeal.dk/public_html/classes/controller/AdminController.php:1389 Stack trace: #0 /var/www/deluxdeal.dk/public_html/classes/controller/AdminController.php(903): AdminControllerCore->processUpdateOptions() #1 /var/www/deluxdeal.dk/public_html/controllers/admin/AdminMetaController.php(437): AdminControllerCore->postProcess() #2 /var/www/deluxdeal.dk/public_html/classes/controller/Controller.php(178): AdminMetaControllerCore->postProcess() #3 /var/www/deluxdeal.dk/public_html/classes/Dispatcher.php(367): ControllerCore->run() #4 /var/www/deluxdeal.dk/public_html/login/index.php(58): DispatcherCore->dispatch() #5 {main} thrown in /var/www/deluxdeal.dk/public_html/classes/controller/AdminController.php on line 1389

 

Can someone help me out with this ?
