Fatal error during finalization placing an order PS 1.7.6

[PanzerkampfPL]

Hi,

I have a problem that some customers who have an account in the shop set up some time ago, when they log in and select the payment and delivery method, they get "Fatal error" when click on the order button.

The problem is independent of the payment method selected and the url to which the customer is redirected is: 
MyShop.com/module/ModuleOfPaymentMethod/validation   for example   MyShop.com/module/ps_cashondelivery/validation

This is what it looks like in debug mode. Only the name of the module responsible for the payment changes, depending on how the payment method is selected.

I would be grateful for hints :-)

1. Please flush any cache that has been built up by the website on the server

2. You should ask them the browser type they are using, and check if the error is happening in only one browser type or all. 

3. When was the site last updated?

Thank you, in total it was very simple. I deleted the browser cache (Chrome) and everything started working properly

Thank you!
