I am developing a Magento site and recently upgraded from CE 1.9.0 to CE 1.9.1. I have noticed that I now have an error when I attempt to checkout as a guest.
1) I select the guest checkout in step1
2) I fill out the form in Billing Information and leave "ship to this address" checked
3) When I continue I get the popup box with the "Please make sure your passwords match" error
In System->Config->Sales->Checkout I have the following
Enable Onepage Checkout = Yes
Allow Guest Checkout = Yes
I have looked at a few suggestions from a Google search, including results on stackoverflow, and although they list the issue in their subject they do not seem relevant. The solutions I have seen seem to relate to passwords not matching and validation issues.
Can anyone suggest a solution to the guest cart login issue that seems to have popped up since the upgrade?
