What’s your forum and blog setup? Is one in a subfolder or are you using subdomains? Have you changed the cookie prefix from the default?So I have tried this out and tried to authenticate on WP with the cookie settings and nothing. Just doesn't seem to work. I am not sure exactly what I am doing wrong but it just won't work and I have read through all the docs twice.
Also, it's still not clear how you get your hands on the plus version. I can't find where to get it.
The Plus version is in our AC Resources premium subscription plan which you need to contact us directly for.
