I used the exact settings as in your guide here: https://gist.github.com/iain-davis/7763251#file-possible-xenforo

But It's saying none of these tables exists? I am running the latest version of xenforo software. I would highly appreciate if you could help me with this issue.

@CommunityFridge Is your database named 'communitybridge', or did you mean to refer to the database used for XenForo?

 # Database Name
  name: communitybridge

@jflory7 My db is named "communitybridge".

Hmmm. Strange. The problem is that it can't find any data in the database, so it seems like your database connection info is likely to blame here.

Is "communitybridge" the exact same database you use for XenForo, like when you installed XenForo?

@jflory7 No it's not. XenForo has it's own separate database.

@CommunityFridge: Could you post your configuration file and white out your database info? The developer will need to see it to diagnose the issue.

CommunityBridge does not use a MySQL database of its own. It modifies the MySQL database of the web application software you are using (i.e. Xenforo). So you need to tell CommunityBridge the name of your Xenforo database, not some other database.
