Paypal Standard Ad on – Auto fill contact and Email from form

The email and name in payment form should actually be prefilled assuming you have them filled in the [adverts_add] form.

They are both in the form but do not show up at the payment form and need to be entered manually.

Hmm, can you paste here a link to your site, so i could take a look at it? Or send it using contact form here https://wpadverts.com/contact/ if you want to keep your site private.
