no response from support yet...

it happens when i try and do stripe test transactions. reuploaded the files a few times in case that was the issue which it doesnt seem to be... this is on the latest 7.9.1

funny thing is on an identical dev install with the same files, templates, hooks everything APART from the live data it works... what is the cause of this issue????
