Can't login directly to vanilla with Wordpress account and vice versa
So, I've implemented vanilla and wordpress sso and login from wordpress site then access vanilla seems to be working.
But if I access the vanilla forum then login there then it won't work unless I've already logged with the account once.
And also, if I logged into vanilla and move back to wordpress site, I'm not logged into Wordpress.
What I'm looking for is perfect log in process.
Like: login and out only once and seamlessly between both. Can anyone guide me ?
