I have the same problem. after installation the only screen I have is recent discussions, no editing of profiles, dashboard, getting started, nothing. I looked at some of the settings and cannot find any setting that might cause conflict.
Works fine for me... I assume your config settings are correct (the plugin setting screen should validate and warn you of issues...) I also assume you are running 2.1 or 2.2 (not 2.3b1 which has few issues)
I set everything up according to the installation instructions. I enabled the embed feature in the actual forums, downloaded and installed the wordpress plugin. verified the forums page and then when I go to the page that it is set to be on its just a blank page.
I would like to know how to set up each oath for social sign in. as I have tried and it does not allow me to sign in via that application, Please make it so a baby could understand with pictures. Granted you do not want to add your own, but parameters that would allow it to work would be fine.
