Added SSL and google font problems

I am unable to resolve two items that indicate problems with making my site secure (lisathegardener.com)
This is the report from whynopadlock.com –

Number of insecure items: 2

Insecure URL: http://fonts.googleapis.com/css?family=Open+Sans
Found in: https://www.lisathegardener.com/cart/

Insecure URL: http://fonts.gstatic.com/s/opensans/v13/cJZKeOuBrn4kERxqtaUH3aCWcynf_cDxXwCLxiixG1c.ttf
Found in: http://fonts.googleapis.com/css?family=Open+Sans

I can’t find any place in the HighEnd/Woocommerce dashboard to fix this.

Thank you for your assistance.

Lisa
