I tried through admin and also through the site at creating an account for one of our existing customers and I keep getting "Invalid Email Address" now I know that its not an invalid email and that the domain is operational and so what is happening??
I really need to get this customers account up and running, does anyone have any ideas?
There is an old thread on this but no satisfactory answer to my issue.
As a test I went through the checkout process all the way up till payment (but didn't do the payment) and it took the address there that it considered invalid when I tried to create a customer account from the admin page. I don't think it's stopped anyone from ordering but I can't be sure.
