http://stardustfactor.com giving this error in the debug - email sent to client says: Error returned from WishList plugin! Command value:ERROR.
I have the latest version of WL, have gone through the setup multiple times and everything is setup as outlined.
I've got a monthly membership version that uses the Subscription button with one ID - and another 1 time purchase using the Buy Now button setup with another ID.
Wishlist is working fine - I added the eStore so I could sell other products and to interface with your affiliate program.
I look forward to your ideas.
