Can't login after authenticated from Salesforce commnity

Dear Team
I am using wordress and latest updated plugin of auth0. I have setup login with salesforce community. It integrates well, however When i try to click login with salesforce , It takes me on my community page where it asks me for user name and password which is perfect. After login on community it takes me back on my site but it didn’t logged in to the site.

I don’t know why and whats wrong with this.
