Google developer tools console shows an error on my front page
Mixed Content: The page at
'https://www.clubmaroochy.com.au/wp-admin/post.php?vc_action=vc_inline&post_id=508&post_type=page'
was loaded over HTTPS, but requested an insecure font
'http://fonts.gstatic.com/s/opensans/v15/memnYaGs126MiZpBA-UFUKWyV-hs.ttf'.
This request has been blocked; the content must be served over HTTPS.
I haven’t changed any fonts on the page for a year or more. Is there a way to use development tools to locate the font it refers to?
