I don't think my site/forum account interlinking is working.

As the title says. I don't think the forum and site account linking is working for me.

Well did your adoptable site already have members before you installed forum? If so, you have to tweak your forum database a lot to make it work. Also the forum integration script was for MyBB 1.6, so if you have MyBB 1.8 you need to change something. Look at this post from Kyttias to fix your problem:

alright yes i did. I had myself and 2 other people registered on the site.
Looks like they'll just have to do things the old fashioned way and register for 2 accounts.
