Can't change order status to "Payment accepted"

[Elfiszcze]

Hi. 

I see this erros, while trying to change the status of the order to "Payment acccepted". It show error only on this status.

An unexpected error occurred. [Symfony\Component\Debug\Exception\ContextErrorException code 0]: Notice: Undefined variable: order_state

 

I use  1.7.7.8 version. 

Is there a way to fix it?

Show the screen from Back office-->orders-->statuses 

Check the ps_order_state_lang table and make sure there is a name for every order state in the ps_order_state table.

Those are the current statuses:

There are 39 in ps_order_state_lang table (in 4 languages) and 39 in ps_order_state table
