Hello @maspohl
The errors you report seem to indicate that the customer/buyer account with which you are trying to complete the checkout does not have a MANGOPAY wallet.
Now, the wallets are supposed to be created on-the-fly for users, if all the mandatory information asked while registering (ie birthday, nationality, person type, etc) is available. If this is not the case, some piece of information about the user is missing.
Based on you user registration form upon checkout, I can see that the user status information is not asked. This is the case when a default “all buyers are…” setting has been setup in the MANGOPAY settings page in wp-admin.
1 – Could you please tell us what the settings are in the wp-admin > MANGOPAY page, for “All buyers are…” and “All businesses are…” drop-down menus?
2 – Could you click again on the [Save settings] button on that page to make sure those settings are enforced?
3 – In the wp-admin users list, could you please check the profile for a user that could not complete the checkout, and look if there is a MANGOPAY wallet, or otherwise an error indicating why the MANGOPAY wallet for that user cannot be created?
I suspect there is something wrong with the default MANGOPAY user status…
Thanks for your help in diagnosing the actual problem.
