Error:One or more fields is invalid
Is there any instructions or screenshots on how to set this plugin up .

Thanks for any help

Hello,
Did you correctly configured your bitpay payment method through your bitpay configuration page via "Hikashop->System->Payment methods". ? can you show it to me through some screenshots for example ?
Thanks

Hi.
here's a screenshot of my plugin page
I've tried different settings but all come back with the Error:One or more fields is invalid.

Thanks for looking.

Hi,

Why have you activate the option "address override" ?
We didn't implement the "bitpay" plugin so it is difficult for us to provide support on a plugin we don't have the knowledge.

What I can told you is that the bitpay call for the creation of the invoice, failed.
It could be a wrong apiKey for the bitpay.com platform.
You should have a log file in the plugin folder (named "bplog.txt"), it will contain more details about the problem.

Regards,

Thanks for the help,
I didn't know about the log file I'll have a look at that .
