I’ve read the other topics on this and read the FAQ but I can’t seem to get this working.
We have a multisite setup.
On the first site paypal works but doesn’t redirect back to the site automatically.
On the second site paypal works again but upon redirecting back to the site we get
error [pp-1102]: Sorry, this order has already been processed or does not exist !
Both sites use different paypal business accounts.
In one of your replys on the forum you mention multisite but don’t explain what the problem with multisite is.
