We have been getting reports from customers trying to check out with paypal that it is not working for them. It returns a “Bad Gateway” error message. Woocommerce has recently updated to version 2.5; the Royal theme hasn’t been updated along with that, AFAIK. Can you test? Will there be an update to the Royal theme soon?
Site URL: hidden Theme version: 2.4 WooCommerce version: 2.5.1
Please check if the issue persists with default WordPress theme.
Also update Royal theme to 2.5.2 version.
Before update delete “woocommerce” folder in the directory wp-content/themes/royal/ and it’ll be reuploaded from a new theme package.
Don’t forget to create back up of your files and database before starting update process!
