Hi Max,
I'm still using the latest version, 1.30 of Lightning on my store (OC v.1.5.6.4).
A couple of times I've gone onto my admin to find the plugin has disabled itself, with the error message:
Real Domain Required
where normally it states the licensed email address.
Can you shed any light on what causes this? Is this something on my end or yours?
Thanks,
Keith Fairley
