The wrong price situation only applies to some customers, not all. The old prices are several weeks old.

I’m running the latest version of estore and the aff plugin. Just reinstalled both plugins corretly, but the report above is from after the reinstallation.

One of the following is happening:

1) Your domain name may not have fully resolved everywhere so some user is still able to go to your old site (which is still on the old host with the old price). Its like they are seeing the cached version of your site.

2) These IPN notifications that you are getting now are for old purchases. If PayPal couldn’t contact your server when you were moving it then they try to send the IPN at a later time.

3) You still have a product with the old price somewhere on your site.

When this happens to another customer ask him/her where they purchased the item from (ask for a link to the page so you can track down where the payment is actually coming from).

It seems like i found a solution to the problem: I had an old deactivated version of W3 Total Cache that i reactivated when i moved to the new server. Not sure if this is possible, but it seems like that plugin had some cached pages with the old prices.

Deleted the plugin and wnt over to Super Cache and now everything looks good.
