We set up the account with one product for the one week free trial and intend to activate the account at the end of the trial.

However, customers have reported they cannot order, and my test order results in this error message at checkout:
10002
Authentication/Authorization Failed
You do not have permissions to make this API call

If I select PayPal payment, the error occurs when I click the PayPal button. If I select credit card payment, the page asking for credit card information appears, but the same error message occurs after I complete the form and click "charge my card."

I have checked the settings and have been unable to locate the setting for "PayPal account optional." As far as I can tell, everything else is correct.

You are using PayPal Pro and it does not seem like you have followed the integration instructions for that. Please switch to the default method "PayPal Standard" in E-junkie seller admin > Cart settings.
