Moving to new host, PayPal no longer functions

I'm moving my site to a new host.
I have reinstalled the cart and imported the database. All successful.
It all seems to be working.
However, at checkout, the PayPal Icon is not shown.
Checking the admin payment module for PayPal, it all looks good.

The only difference is that the old site was domain.com, the new site is domain.net.
Is this the issue?

Same PHP version, same Zen version 1.5.7c

Wait, there is another difference. I don't have SSL installed on the server yet. The icon path is https:// so that may explain the missing icon, but if you just click continue, you get a odd PayPal page with a login warning. This maybe due to no SSL also

Get your SSL installed ASAP and keep your store in down for maintenance until then.
