PHP Fatal error: Undefined constant MODULE_PAYMENT_PAYPALDP_MERCHANT_COUNTRY

Zencart 1.5.8a - PHP 8.2 - No Plugins - Fresh install w/upgraded DB

Hello, I am getting this error with a fresh install and upgraded database.

PHP Fatal error: Uncaught Error: Undefined constant "MODULE_PAYMENT_PAYPALDP_MERCHANT_COUNTRY"

/home/dev/public_html/includes/modules/payment/paypaldp.php:264

Because of the error the payment modules page only loads halfway, stops right after Paypal Payments Standard. It also affects the orders-edit page with just a white screen.

Any seen this before?

Thanks

Have you set your country in

Configuration >> My Store > Country

Go to Admin > Modules > Payment and click on the PayPal you have installed. This will fix your installation.

Unfortunately, it won't. Apparently the previous database has paypaldp enabled, but that version didn't have the MODULE_PAYMENT_PAYPALDP_MERCHANT_COUNTRY setting defined.

That setting's added in the module's check method, but the processing doesn't get that far due to the PHP Fatal error due to the constant not being defined.

Noting that another issue is that the setting is either USA, UK or Canada, but various comparisons in the module check for US instead of USA.

So uninstall/reinstall?

And lose all the configuration setting from the previous install (that you can't view due to that fatal error)?

Should line 264

        if ( ((MODULE_PAYMENT_PAYPALDP_MERCHANT_COUNTRY == 'US' || MODULE_PAYMENT_PAYPALDP_MERCHANT_COUNTRY == 'Canada') && (MODULE_PAYMENT_PAYPALWPP_APISIGNATURE == '' || MODULE_PAYMENT_PAYPALWPP_APIUSERNAME == '' || MODULE_PAYMENT_PAYPALWPP_APIPASSWORD == ''))

be

        if ( ((MODULE_PAYMENT_PAYPALDP_MERCHANT_COUNTRY == 'UK' || MODULE_PAYMENT_PAYPALDP_MERCHANT_COUNTRY == 'Canada') && (MODULE_PAYMENT_PAYPALWPP_APISIGNATURE == '' || MODULE_PAYMENT_PAYPALWPP_APIUSERNAME == '' || MODULE_PAYMENT_PAYPALWPP_APIPASSWORD == ''))

Ok so I tried updating line 264 like this.

if ( ((MODULE_PAYMENT_PAYPALDP_MERCHANT_COUNTRY == 'USA' || MODULE_PAYMENT_PAYPALDP_MERCHANT_COUNTRY == 'Canada') && (MODULE_PAYMENT_PAYPALWPP_APISIGNATURE == '' || MODULE_PAYMENT_PAYPALWPP_APIUSERNAME == '' || MODULE_PAYMENT_PAYPALWPP_APIPASSWORD == ''))

Unfortunately, this did not work for my case.

However, I added this right above line 264

define('MODULE_PAYMENT_PAYPALDP_MERCHANT_COUNTRY','US');

This allowed the payment module page to load completely. Once loaded I

*Took screen-shots of all the settings.
*Clicked Remove Module
*Clicked Install Module
*Entered my settings
*Then removed my define

define('MODULE_PAYMENT_PAYPALDP_MERCHANT_COUNTRY','US');

This process added the correct entries to the db.

So far everything seems to be loading correctly.
