Hello,

We process some test directly on your website and wasn't able to reproduce your issue, so :
- Can you process a test with another user account? With another browser?
- Provide a detailed step by step to reproduce the issue (be very specific url link to product as a start, and each step details everything).

Another thing, note that if we refer to your error message, it seems (to be confirmed) that HikaShop is not involved in the cause of this error.
Regards
