I'm curious, has anyone got an installation of ATA 3.6.7 and Wishlist Membership? I've had it working before but they are now telling me that the reason the Registration doesn't work is the theme.
I've used ATA with this product before and no problems. I'm going to try with 3.6.4 and see what happens and if I have to revert back to the previous version of Wishlist. (They just had an upgrade)
