after changing domain name cart not working

I changed my domain name from dev.collabora365.com to collabora365.com. I redid my product links -- inlcuding re-encoding -- and now when I click on them I get a blank shopping cart page. (except domain registration)

Moroever, I am unable to request support from dashboard or grant access. I tried switching with the disabel/enable site option and that does not work

I was hoping to go live today. I will be very disappointed if the plugin is stopping me
