Blank Screen

ok i tested it so far. when i have enough points it seems to be ok. i revceive a mail and the site confirms my order.
when i have not enough i receive no error or something else. there is no information that i havent enough points.
i get logged out and nothing happens. In the backend there is a canceled order. hm

I just tryed at vmvendor.nordmograph.com and here is what you should get:

"You do not have enough points (only 26463) for your order total amount (200100). Order will be cancelled."

It doesn't log me out and takes me back to my cart with my products in.

Do you have other Payment plugins that cancel the order correctly without loging you out?

I really don´t know the reason for that. Yes i tried the standard payment plugin! It works like a charm.

Are you trying on a local setup or is your site online ? Can I have a look ?
