 * Hi Support
 * I have a site that is throwing off an error on live settings but on Sandbox it
   is working fine.
 * – I am using the settings on two identical sites
    – I changed the other one to
   sandbox mode with sandbox details and no errors on checkout – but the live one
   is throwing this error – client did not verify email yet but has bank attached
   already – they have tried this several times on live and error is below ( [TOKEN]

 * Hi [@fredbangkas](https://wordpress.org/support/users/fredbangkas/),
 * The error code `10001 L_ERRORCODE0` is very specific, and has a few items that
   may affect this.
 *  – The error can be related to the domain. Do you have an underscore in your 
   domain, or is it a sub-domain? Sometimes PayPal has issues processing the type
   of domain if it has a special character such as an underscore.
 * – Internal Error usually means that it is an internal PayPal error. From the 
   [PayPal documentation](https://developer.paypal.com/docs/classic/express-checkout/integration-guide/ECReference/#troubleshooting)
   this is usually related to the settings with the Business account in PayPal’s
   side.
 * Please reach out to PayPal and double check your business settings, and see what
   they say. Let us know the response!

 * Hi nixiack8
 * Yeah I think it was because Business Merchant was not verified by the owner thru
   the email. She said it is working now.
 * Quick Question can I use 1 business merchant API settings on 2 different sites
   although the owner of the sites are the same person.?
 * Thanks for your reply

 * Yes, you can use the same PayPal account on multiple sites. You cannot, however,
   use multiple PayPal accounts on a single site, within the same plugin settings.
