Chrome Insecure Content Block SSL

Hello,

Im trying to make this wordpress site fully complient with ssl and when I go to chrome browser<tools<javaScript Console. This pops up:

[blocked] The page at https://therapycollars.com/shopping-cart/ ran insecure content from http://fonts.googleapis.com/css?family=Lato:100,300,400,100italic,300italic,400italic|Droid+Sans:400,700.

I dont understand where this is or how to fix this…any advice?

Thanks,
Brandon
