We have developed a site on a Siteground server where the Woo login/log out works. We have now moved to Kinsta and it does not work.
I have talked long and hard with Kinsta and they insist it is not a server problem, but a dev problem, probably in the theme (i am not so sure about this though):
“Please understand that this is a development issue, probably with theme, which is out of our scope of support. It’s not a server level issue. We’re using always the latest version of nearly everything and we have custom rules in our Nginx configuration, but if you check the articles below, these are coding level based problems.
My best guess is that the method you’re using for the logout is probably deprecated.

If to try to explain the issue:
*On Kinta server (www.cubscartel.com):*
– I cannot login as it will not log me out. It never shows login screen.
– When trying to log out I am thrown to first one page (https://cubscartel.com/wp-login.php?action=logout&redirect_to=https%3A%2F%2Fcubscartel.com%2Fmy-account%2F&_wpnonce=11ace8980f) where I have to confirm the logout, and then to wp-admin screen (https://cubscartel.com/wp-login.php?loggedout=true)
*On dev server (www.cubscartel.muddycreatures.greatsimple.com:*
– I can login.
– I can log out and when logged out I am directed to the my-account login screen.
