"One Page Checkout" "Terms Of Service" checkbox tricky issue

[MonDeveloper]

Hi guys, I'm facing a strange and not reproducible bug that is driving me crazy.

 

Couple of days ago I launched our new WebStore and everything runs smoothly until I noticed we had too much abandoned chart, at this point our customer care contacted all the customer just to ask them about the reason and incredibly more than few told us when they click on the TOS checkbox nothing happens and the payment options don't appear.

 

We double checked the customer addresses nation and the configuration of the payment method, we also verified the checkbox mechanism is working under all the browsers (IE, Chrome, FF) and verified the customer were using one of them; we also double checked with customer both using Tablet and PC but sometimes nothing happens.

 

We trust our customer and the fact many of they all around the world told us the same thing let me think there should be a real and tricky problem behind this.

 

Does any of you ever faced something similar?

 

Some suggestion on how to face it?

 

Thx guys, have a nice PS ecommerce,

Hi mM

Started checking from the same start point (TOS) and discovered the following in OPC.

Same attribute when make new cart and after login as member

SO checked server errors and saw json_encode issue which was a fault in code of one Payment module and stopped all Payment modules from showing up.

Try to remove payment modules to check if one of them is giving you trouble. I fixed the code in the extra module and everything is fine now. Something wrong with encoding.

Hope this helps
