ReflectionException

[Radu.S]

Hello all,

I am working on a shop and I tried to simulate a customer account creation and order placement. After I finish creating an account I get a white page. Same thing happens when I finish an order. Also, when trying to send a support email as a "client". After turning on Debug mode, I find the errors posted below (I know, it's a long list...).

I did not modify anything in the php files. Also, the problem exists no matter what theme I use (even classic theme).

The orders and customer accounts do appear in the backoffice.

Has anyone had this problem? Could you please help me to find a solution?
