问题
I manage some WordPress/WooCommerce online shops which have been running problem free for a few years. Recently, we have noticed that our transactions via Paypal have not been working.
I tried to process an order myself using PayPal and got the following error:
We’re sorry things don’t appear to be working at the moment. please try again later paypal
WooCommerce have suggested it's not a problem with their software but most likely a problem with the specific PayPal account. As usual, PayPal support is saying "there's no problem with PayPal"
Without pulling apart the WooCommerce code, I'm not sure where to go next...

Issue : Customers are receiving error: Things don't appear to be working at the moment. Please try again later.
This error typically occurs for two reasons:
1.) You have entered your PayPal email address or PayPal Identity Token incorrectly. Please confirm your PayPal email address and PayPal Identity Token are entered correctly within Downloads => Settings => Payment Gateways => PayPal Standard
Or
2.) Your customers may also see this if Encrypted Website Payments set to ON. Setting it to OFF will resolve the issue. This setting can be adjusted from within your PayPal account by navigating to Profile => Profile and Settings => Selling Preferences => (Website Payment Preferences/Website Preferences) and selecting OFF under Encrypted Website Payments

Check paypal setting at Admin panel and Paypal account both https://docs.woocommerce.com/document/paypal-standard/

Your Instant Payment Notification (IPN) URL must match your store's URL
Under Profile & Settings > SElling Tools > Instant payment notifications Click update, then add your store's URL
You also need to check API access > NVP/SOAP API integration (Classic) In the section Credential Signature , find these values and submit it to your Woocommerce payment settings
- API Username
- API Password
- Signature

I tried everything then came across a post and fixed the issue. It had something to do with Memcached. I uninstalled it and now my customers are able to pay with debit and credit card. https://simonward.net/paypal-checkout-error-when-paying-with-credit-or-debit-card/
