Hi/hej!
I’m having the same issue. From what i have gathered it might be because I am running test from a “staging.domain.com” kinda situation. When the checkout fails i get redirected to domain.com and the {“error_code”:”READ_ONLY_ORDER”,”error_messages”:…. is displayed in orange.
Running Version 2.1.3 & 1.5.4
Could this be caused by the staging.domain.com redirected to domain.com after the initial purchase phase?
Thanks in Advance
