Tracking down errors

I've received this cron report:

<div style="border:2px solid red;padding:4px;width:600px;margin:0px auto;">
                    <div style="text-align:center;background-color:red;color:white;font-weight:bold;">Error</div>
                    <div style="text-align:center;">Database query error</div>
                            </div>

I was wondering what this error is about?  I have installed a new template which I think this problem relates to.  I'm getting hundreds of emails on this particular error.

Would appreciate any help or insight.

You have a Databse Query Error. So something is trying to run a query to your database and it is not working. Is this the complete error that you are getting in your cron? If not, please post complete error (minus any security related items such as db username and pwords)

You may need to turn on database debugging in /inc/classes/BxDolDb.php:

define( 'DB_FULL_DEBUG_MODE', false );

define( 'DB_FULL_DEBUG_MODE', true );

Get the full error, post, and then revert the line back to false.

 Yeah this is the complete error.  I'll have to do what Nathan said and get the entire error report.

 Before you dump it here, please make sure there are no usernames and passwords in the log

It turns out to be a module that relied on other modules that I had uninstalled.  So I uninstalled it, and the site improved.  Shame I can't use the module though.
