The only place that email shows up is in the eStore Customer table. Could this be the issue? – No
Lets try to address this step by step…
I just visited the following URL and was able to sign up for an account (I guess you have free membership turned on?)
I noticed a few things that are odd:
1) The “Membership” field doesn’t have any value? This is not right as it should state the membership level name.
2) Clicking on some links on your site brings up a lightbox thing but it hangs in the middle. Not sure what sort of plugins you are using but this behavior doesn’t seem right and can cause other JQuery related issues.
3) Your site seem to be taking too long to load a page (Is it just me or this is normal?)
Anyway, can you please post a link to the page where you have your payments button so I can do a purchase and see how that goes. The only thing with sandbox purchase is that the sandbox email is not a real email so when the plugin sends the email with the unique link to complete the registration I won’t get it. Maybe you can create a $0.01 “Buy Now” button and hook it to a membership level so I can test it live?
