Website SSL; Insecure Data (no padlock)

I'm not sure what changed, but sometime recently something changed that is now causing my padlock to not show up on the website. It appears for a minute and then it goes away, I'm assuming something is loading that is not secure.

I'm using the "Why No Padlock" website and its showing secure except for that "0 Items" were downloaded during the test, which is weird and I'm not sure what it means.

Any help would be appreciated to get the lock to re-appear.
