PayPal Standard Not Working in NOP 4.5

I have been working for weeks configuring a new website for my business. I'm attempting to use the PayPal Standard Payment method. I've followed all of the configuration instructions however, it tells me no payment options available when I attempt to do a simple checkout.  Need some help.

I assume you have configured the pluign and enabled the payment method ?
And the plugin is the v4.5 version
Any errors in the log ?

Hello Yidna,

Thank you for the response. I've checked the log tables in the DB and I don't see anything pertaining to this problem. I see several of these;

I am to nopCommerce, I watched all of the training videos and I've been coding with .Net since it's inception. I started coding in 1982. Hope you can help.

Those errors are because the email account is not configured

That is the contents of the Plugin.json file.
I can send you screen shots of the Payment setup screens if you want.  I followed the instructions on the configuration. PayPal standard is the only payment method I have active.

What is your setting paymentsettings.bypasspaymentmethodselectionifonlyone ?
If it is true and you only have one method then there will be no selection displayed
So you wont see Paypal view until you complete the order

Did you go through and complete the order ?

It is False.

When I try to continue on the screen that says "No payment methods available" it will not continue.

I found the problem!! It was in payment restrictions. I had clicked on the PayPal standard check box at the top of the country list and it selected all of them. I had to uncheck the one for the United States.

Thank you so much for your help. My new website will go live in January. Funderlandrents.com, we rent inflatables around the Corpus Christi Texas area.
