OK, please close, seems it was only not working with Safari. Must be a weird issue there.
Also, Archimedia, I suggest you start your own threads instead of hijacking one from someone else. It complicates the support process, creates noise in the thread and generally is frowned upon in the community.
Marcin,
I am seeing a 500 error now on cart and checkout. Any idea why?
Thanks for your help. We are trying to get this sorted to go live next week.
Happy to give a glowing endorsement once we get it working.
Thanks,
Andrew
