Determining which resource is causing SSL warning

Question

I have a website with an SSL cert, but instead of displaying a green lock, google chrome shows a lock with a red cross on it and displays a warning that the page has insecure contents.

I understand that the cause of this is when you use a resource (image, js, css) that is not being brought over via HTTPS.

I have checked the 'net' tab in firebug, and every resource is over HTTPS. Thus I cannot figure out what is causing the warning in google chrome.

Is there a way to find out which specific resource is causing this to happen?

could it be the database connection?

I've had Chrome cache issues with this before. If you're sure you've nabbed all the culprits try clearing your cache and history.
