Ok.
First of all. I have rolled back to version 1.6.4, which happens to be working just fine on my website.
Secondly, I’ve copied-pasted the exact same error I was getting at the top of my checkout form. This is it again:
[The value of a field does not conform to the expected format]
So the screenshot will show you the exact same message, and I don’t intend to switch to your updated version, for fear of having issues with my clients. Please sort this out.
Thirdly, where do I find the Paylog file again? I’m totally confused here.
Fourthly, you said I should mention the method I was using? I simply placed an order on my own website, and usually, the credit cards fields are supposed to be displayed, for me to fill out my details. It wasn’t the case with your plugin update. The credit card fields would display normally with version 1.6.4. But when updated, I get the error message.
So please clarify, when you say I should explain the method I used.
Looking forward to your reply.
