I get Session does not contain antiforgery ID when logging in

[emmigereb]

Hello
I would need some ideas to test and make i work.
I use the plugin on several sites, all hosted on Azure App Services. Some sites are Windows and some are Linux based. This one is Linux - Nginx. I tried several things i found others posted in different issues but until now nothing seems to help.

Here is link to the site: https://www.cm1.se/
Any help is welcome, I would need this to make it work soon.

Azure says they can't find why we are getting this message. And I have no idea what to try to solve it. So unless there is someone with a good suggestion we will have to change to another plug-in. Which by the way is not something I want :(

Check your session configuration on your php server. Found that mine was a result of an invalid session_save path.
