Hi @laszloszalvak,

I turn on the debug mode and here is the error for both Google and Facebook “Error: Unable to validate CSRF state”. Thank you

Hi @nextend_ramona

It is not the server. It is my caching plugin. When I turn off the caching plugin everything work just fine. Thank you for your help. I will ask the caching plugin developer on how to solve this issue. Once again thank you very much for your help.
