I am setting up an online store with WordPress (4.7.4) and Woocommerce (3.0.5). I cant get PayPal Standard to work. Once I choose it as a payment option on the front-end and I proceed to pay, I get an error from paypal that says:
“Leider ist ein Systemfehler aufgetreten. Versuchen Sie es später noch einmal.“. Couldnt find the english error page so I’ll translate: “Unfortunately, a system error occurred. Please try again later.“
I called PayPal support and they havent received any errors from their side or my account.
I installed PayPal for WooCommerce and used their PayPal Express checkout. Although buggy, and a payment went through. However, I want the normal PayPal Standard from WooCommerce to work.
You can order something for free using the coupon code “stackoverflow” to test at www.esteemabaya.com.
I also couldnt figure out if it was one of my Plugins used? Here is a list of Plugins:
Woocommerce Advanced Bulk Edit
WC Password Strength Settings
W3 Total Cache (I have set all settings according to WooCommerce recommendations)
UpdraftPlus – Backup/Restore
Hyyan WooCommerce Polylang Integration
