The site http://www.jotunn.is is now on HTTPS but Google Chrome says that the site is not fully secure because of one link that is in the CSS code. The link is url(//theme.co/x/demo/integrity/9/wp-content/uploads/sites/10/2013/06/bg-integrity-91.jpg in some x generated CSS on my site.
Can you help me remove this since I don’t think this is needed or at least change the URL to https ?
Please try set an image under Customizer > Layout and Design > BACKGROUND OPTIONS > Background Pattern. Then click Save. After that remove that image then click the save button again.
