Yes, I solved the problem.
It has to do with you now having https:// URL instead of https:// you used to have
1 – Needed to force secured check out in Woo Settings
2 – Also, in your site’s settings, you need to change site’s URL so it reflects https://
Does this make sense?
If you need more details, let me know and I will try to share more
Hope it works ??
