How are you using Google fonts? Is it in the theme blueballfreestackresponsive?
I see an import statement right at the top of the consolidated CSS file. Hard to tell where it’s coming from since you have the consolidated CSS turned on. The font name you are looking for Source Sans Pro( the %20 are spaces), also using Ubuntu font.
Thanks for the advice @teefers I think I have sorted it. Found the fonts in the CSS folder of the theme style. Changed the guilty party to https and republished. Looks like it sorted now.
Mysterious! I have found that unsecure web-font calls don’t stop the https padlock. I found a load of these and thought they were the cause of a missing padlock. However, the only fix I need to do was an unrelated Trip Advisor widget. The font calls had no effect even though they are all showing as an issue on whynopadlock.com
