Paypal account upgrade - "invalid business" error


Well-known member
In the user_upgrade_log I get "invalid business" error after users successfully purchase an upgrade. Any idea why?

The email address that PayPal is reporting as being paid isn't the email that you entered into the XF control panel. You should see a business value in the PayPal callback - use that instead.


Note that XenForo requires a premium/business account as far as I remember, in order for these purchases to go well, and that it has to be the primary paypal email address.

Apologies if I am wrong, I remember reading about this the other day while looking for something else (attention span wasn't focussed on this topic).

I used additional email instead of primary email address for my Paypal account. After changing it to primary it works as expected. Thank you.
