Hi, I have been trying for days...
This is what I have. A main WP site on gringo-rio.com where the vanilla forum is embedded. The forum installation resides on a subdomain called therioforum.gringo-rio.com (in a folder in my bluehost account).
I have plugin Vanilla forums installed. I tried to set it up through that one but had no success.
I also have WP Vanilla Connect installed, but it doesn't seem to work.
I am sure I have overseen something, please help if someone can!
